Amazing potential
I honestly loved how this drama begun. I’m a fervent fan of action / mystery dramas, especially Korean. I make sure I watch one as soon as it’s released. Therefore, speaking from experience, the plot was good. Revenged based, yes. I’m aware there are many revenge based kdramas but Agent Kim Reactivated followed a path that makes it a little different from the others. Especially, the fact that Kim’s identity was completely unknown to his daughter and so was his previous nationality.Which is why I liked how Min-ji always stood her ground despite not knowing who her father actually is. It shows how she’s naturally a cool girl.
However, the drama obviously contains its own flaws. The very first and foremost flaw was the SMD. I don’t think there was any need for their involvement in Kim’s business to be this prominent. At least not until episode 7-8. Yes, they had their importance but still not so much to the point that they had to be up in everybody’s nose like that. They diverted the drama from its actual plot and purpose as well. It was supposed to be revenge-based which, yes, it largely was but their involvement did stir up things a lot. They should’ve just laid low until they arrested Kim and Ri Eung Ryeong appeared in the South. That way, they could’ve portrayed their importance in a better manner as well.
Next, Ju Gang Chan. What can we say about this guy? Got involved for no reason just because of his useless daughter. Like, I totally understand that this is what forms the basis of the drama. But really, it gets annoying after some point. It’s not realistically possible for a man so rich to love his daughter, who brings absolutely no use to him and has the potential to cause impeccable damage to his reputation, so much. Anybody would agree that it’s unrealistic. I understand he must love her but definitely not to the point that he would join forces with the North just to take revenge on his daughter’s enemy’s father. This had more to do with his ego that Kim hurt. However, that again merely leads back to his daughter, Hye Ri. I liked how he got humbled every time though.
Nonetheless, I would conclude it’s a good drama with good thrill. High rewatch value as well

Agent Kim Reactivated is one of the more enjoyable Korean action-comedy dramas of 2026. The series balances family moments, humor, and espionage surprisingly well, and much of that success comes from So Ji-sub's performance.
One reason So Ji-sub feels perfectly cast is that he has played undercover and secret-agent-type roles before. He has the calm presence, experience, and natural charisma needed to make a veteran operative believable. He doesn't have to force the tough-guy image; it comes across effortlessly. At the same time, he gives Agent Kim enough warmth to make the family scenes work just as well as the action sequences.
My favorite part of the show was the relationship between Agent Kim and his daughter. Their interactions added emotional weight and prevented the series from becoming just another spy drama filled with gadgets and fights. The daughter was a genuinely likable character, and the family dynamic gave viewers something to care about beyond the missions.
I also enjoyed Agent Kim's friends and teammates. They brought a lot of personality and humor to the show, creating a sense of camaraderie that made the team feel believable. Their chemistry with So Ji-sub was one of the highlights throughout the series.
The only major issue I had was the portrayal of the spy agency chief. This is where I think the show lost about 1.5 points from what could have been a near-perfect score. Instead of feeling like the head of a modern intelligence organization, he looked and behaved like a cartoon character from an old American comic book. The long outdated coat, the decades-old cap, and the exaggerated mannerisms made him feel completely out of place compared to the otherwise grounded tone of the series. Every time he appeared, it felt like he had wandered in from a different genre.
Despite that flaw, Agent Kim Reactivated remains a highly entertaining watch. Strong performances, a likable cast, solid action, and heartfelt family moments make it easy to recommend. So Ji-sub once again proves why he is one of the best actors for these undercover-agent roles, carrying the show with confidence and charm.
Final Rating: 8.5/10 ⭐⭐⭐⭐⭐⭐⭐⭐½

i am very bias when it comes to so ji sub's actorism
i just watched this because so ji sub is the mc and yes, it's still ongoing but i just couldn't help but type this. it's fantastic. yes, i know this is an overused plot and they just keep dragging it but the mc is so ji sub for god's sake!!!!!!!!!!!!!!! he doesn't make it cringe (at least, for me). i love looking at his sad eyes, the guy is not only a fighter but he could portray sadness well too! u can see it in his expressions, instead of just fighting the goonies. I REALLY REALLY LOVE THIS. I LOVE MERCY FOR NONE TOO.and this just inspired me not to have any social media presence or be this biggie something. i am someone who thinks if i dont have any social media presence or if i don't act friendly to others, i'll die. but watching this just made me think "oh nothing's really gonna happen, u'll just live" so it really help!!!!!! helped me build this alter ego of being mysterious and all of that shenanigans.

A Drama About Love Disguised as a Spy Thriller
Agent Kim Reactivated is a revenge-action thriller about Kim Do-Hyeon (Manager Kim), a retired covert operative who is forced to reactivate his old identity when his daughter disappears. But beneath the espionage, conspiracies, gangsters, betrayals, and political games is a story about human bonds and what people are willing to sacrifice for one another.On paper, the plot sounds familiar. Kim Do-Hyeon lives a quiet life as a bank manager and single father after abandoning a dangerous life as an elite operative. When his daughter is abducted, he resurrects the skills and identity he buried years ago to save her. What makes the drama work, however, is that the rescue itself becomes a vehicle for exploring several different kinds of relationships: parent and child, friendship and brotherhood, loyalty between comrades, loyalty to country, loyalty to principles, and the betrayal of those loyalties by institutions.
The show repeatedly asks a simple but powerful question; what is loyalty worth if the people you are loyal to treat you as expendable? Governments, intelligence services, criminal organizations, and powerful businessmen all speak about loyalty and sacrifice. Yet many of them casually discard the very people who gave everything to them. Meanwhile, the strongest forms of loyalty come not from institutions but from ordinary human relationships. That contrast is, in my opinion, the real emotional engine of the drama.
As for the acting, it is no surprise that So Ji-sub is the soul of the series. True to form, his greatest strength here is not the action scenes, though those are excellent, but his ability to communicate pain, exhaustion, regret, and determination with very little dialogue. He conveys everything, especially in the moments that matter most, through his expressions and presence alone. Kim Do-Hyeon is not portrayed as an invincible action hero. He is a grieving husband, a frightened father, and, most of all, a man constantly questioning whether his past destroyed any chance of a normal life.
For me, the most memorable scenes are not always the fights. They are the moments where you can see a father realizing that the quiet life he built for his daughter may never have been enough to protect her. There is an almost tragic quality to Kim. He is not fighting because he enjoys violence or because he misses being Agent 66. He is fighting because he has run out of alternatives. That distinction gives the drama tremendous emotional depth.
One of the strongest aspects of the series is the friendship between Kim Do-Hyeon, Seong Han-su, and Park Jin-Cheol. What I especially appreciated is that Kim does not have to carry the entire drama on his shoulders. Many spy dramas focus on romantic chemistry. Agent Kim Reactivated's strongest chemistry is actually between these three middle-aged men. Their relationship feels earned. These are not friends because the script tells us they are friends. They are men who have shared trauma, shared missions, shared losses, and years of silence. When Kim needs help, they do not stop to ask whether helping him is wise. They simply show up. That is one of the drama's recurring messages: love is an action; loyalty is an action. Not a feeling. Not a speech. An action. Their friendship becomes a direct challenge to the selfishness and corruption surrounding them. In a world where institutions repeatedly fail people, these men prove that genuine loyalty still exists.
As far as I am concerned, the reason the stakes feel real is that Min-ji could easily have become a simple "kidnapped daughter" plot device. Instead, she represents everything Kim spent fifteen years protecting. She is his future, his redemption, his promise to his late wife, and the reason he abandoned his former life and chose family over service to country. That is why the story ultimately becomes a battle between two identities: the agent and the father. What makes the drama so compelling is that Kim rediscovers Agent 66 because he is a father, not in spite of it. His love for his daughter becomes stronger than his desire to remain hidden.
Many reviews I read before the drama ended focused on its geopolitical elements and viewed it primarily as a thriller involving North and South Korean intelligence. To me, however, the political conflict is largely symbolic. Throughout the series, we see how agents are used by governments, how operatives are treated as disposable assets, how allegiances shift, and how secrets destroy lives. We see institutions demand sacrifice while rarely repaying those who make it. What I admire most is how the drama quietly asks whether loyalty to a nation should outweigh loyalty to the people we love. The answer it provides is surprisingly humanistic. The characters who survive emotionally are the ones who prioritize people over systems. The villains often do the opposite. Even when they seem to flourish, their victories are temporary because they have sacrificed their humanity in pursuit of power.
I would be remiss not to discuss the action because it deserves considerable praise. The action works because it reflects character rather than existing solely for spectacle. The drama never presents Kim as a young superhero. Every fight feels brutal, personal, and costly. When he fights, it is usually because his daughter is in danger, his friends are threatened, or someone vulnerable needs protection. The violence therefore carries emotional weight. It is not entertainment for its own sake. It is an expression of desperation, fear, and determination.
I think one of the biggest reasons for the drama's success is the chemistry among the cast. The father-daughter relationship between So Ji-sub and Seo Su-min grounds the series emotionally. Even when they spend much of the story apart, their emotional connection remains the driving force behind every decision Kim makes. Equally impressive is the chemistry between So Ji-sub, Choi Dae-hoon, and Yoon Kyung-ho. Together, they create a completely believable sense of lifelong camaraderie and trust. Their friendship feels authentic because it is built on shared history, mutual respect, and unwavering loyalty.
The antagonists are equally effective because they embody different forms of corruption: power without responsibility, loyalty without morality, and authority without compassion. They are not merely obstacles for the heroes to overcome. They represent the cold systems that place ordinary people in danger and then treat them as expendable.
If someone asked me what Agent Kim Reactivated is about, I would not say it is a story about a retired spy rescuing his daughter. I would say it is a story about a man discovering that the relationships he built are worth more than the identity he sacrificed. The series argues that family is not defined solely by blood. Friendship can become a form of family. Loyalty must be earned rather than demanded. Love is measured through sacrifice. Governments, agencies, and organizations often forget the human cost of their decisions, but individuals do not.
In the end, Agent Kim Reactivated is not really a spy story. It is a story about people who refuse to abandon those they love, even when doing so would be easier, safer, or more rational. The spies, conspiracies, and action are simply the framework. The real story is about the bonds that survive betrayal, time, distance, and even war. And that is why the drama resonates long after the final fight is over. I, for one, look forward to a second season.

Code-66: When a Lethal Black-Ops Asset Fails Basic Parenting 101
The premiere of Agent Kim Reactivated doesn’t just give us a standard high-octane revenge thriller; it exposes a brilliant, deeply ironic root conflict. We have So Ji-sub playing an absolute powerhouse of a covert operative—a literal human weapon—who is completely, utterly incompetent when it comes to the simple domestic laws of survival: understanding his own daughter.While many will inevitably look at this adaptation through a pure genre lens and expect a relentless, Taken-style action-fest, the real genius of the opening episodes lies in its depiction of the devastating consequences of the "strong, silent" archetype. Agent Kim’s stoic, emotionally unavailable approach isn't just a character quirk—it is a foundational parenting failure. By substituting deep, vulnerability-driven communication with superficial provision, he leaves his daughter completely unequipped for the brutal social hierarchies of school bullying. The real tragedy of Episode 1 isn't that his dark past caught up with him; it’s that his emotional absence might have driven his daughter into harm's way long before the syndicate ever did.
The series now stands at a critical narrative crossroads. It can easily sink into an empty, stylized cycle of endless combat choreography, or it can swim to greatness by treating the violence as a secondary catalyst. For Agent Kim Reactivated to achieve masterpiece status, the ultimate tactical mission cannot just be a rescue; it must be a reformation. The real victory won’t be Agent Kim taking down an empire with his bare hands—it will be him learning how to look his daughter in the eye and finally become a real father.
So Ji-sub’s phenomenal, micro-expressive acting gives us hope that this character has the emotional depth to pull it off. Let’s just hope the writing chooses to prioritize family restoration over empty political tropes and cheap shock value.
Initial Rating: 8.5/10 — A masterclass start with a brilliant emotional core. It has the blueprint to be something profoundly human if it doesn't lose its soul to the bullets.

Dropping because it has anti pa l estine sentimentcouldn’t they keep the propaganda to only north korea and south korea? why involve a population that is already suffering so much. That’s so cruel and horrible did not expect this from them at all. My morality stops me from watching it further sorry i can’t ignore or act like it’s a different country

MERCY FOR NONE PRO MAX
Popular plot, ahjussi retires from the military, becomes a husband, and lives a quiet disguised life, until the killing spree starts. Feels like Mercy for None part 2, same storyline just tweaked, with friends joining in this time. I really hope he lives this type of role alone and enter his villain role..Kdramas really need to learn how to blend the KopiKo into the plot better, it’s been over a decade.
Am I still watching? Yes, but only for vibes. At least the cast is stacked with amazing actors!!

They used AI Generated scene
This series had me hooked the moment i saw So Ji Sub. And the plot looked really intriguing to me and it was like a Korean version of John Wick. And i really enjoyed the first episode. But as i was watching backstory scene of Manager Kim, the whole black and white scene looked off. The shots, environment and characters faces looked really off. Then I noticed that it was AI generated scene. And some people think it's not a big deal and don't care about it. But to me this matters a lot. it's just insulting to human's artistic side and skills. It takes lot of time and commitment for people to learn certain skills and knowledge and it's no different with people who works behind the scenes. Film director, art director, production designer, camera operator and so on. Even the Actor and actress. All of these talented people come together with years of knowledge and experience to create these incredible masterpieces. But then using generative AI is just like ripping out their entire work and producing soulless slop. I mean i understand why they did it. It will reduce the cost for the budget. But that doesn't make it justifiable. If it was used for only few shots, that would've been fine. But a whole damn multiple scene? It is unacceptable.Was this review helpful to you?
Good. Only some Islamists from SEA or other places are losing their head over a genuine fact.
Till now, great story.Idaf to those Islamists who are saying Why Palestine and Pakistan !!! Dumbos so Hamas didn't carry terrorism over Israel in October ?? Israel didn't feel itchy to attack and wipe out Palestine all of a sudden.
And fvckin Pakistan !! It IS the land, the home of Islamic terrorism. The Army continues to breed terrorism there. Where was Osama Bin Laden found again ?? Where are the leaders of LeT and JeM (Lashkar e Taiba and Jaish e Mohammad) Hafiz Saeed and Masood Azhar are freely living again ??? In Pakistan only.
Why are Muslims from SEA and other nations so deluded to accept this fact ? The fact being 99% of terrorist groups are Islamic and they breed in such countries ??
Ig ore those haters. Add the drama to your watchlist.

A Legend on Paper
Agent Kim Reactivated is a thriller that spends more time telling you its protagonist is a legend than showing you why. Between endless flashbacks, macho posturing, and characters endlessly reciting his résumé, the search for his daughter becomes an afterthought. It clearly aims to be a mix of Taken and The Bourne Ultimatum, but ends up feeling like a thoroughly mediocre parody.Was this review helpful to you?
