The series started off decent enough. I was rating this a 7.0 at Episode 6. By Episode 10, I was completely disillusioned by the terrible writing that didn't really allow Lee Jong Suk, Im Yoon Ah and Kwak Dong Yeon to display a wider range of their acting skills. Surprisingly for me, Yoo Tae Joo is probably the best thing to emerge from this chaotic, confusing mess.

This series spent more than half of its episodes in the penitentiary. It wasted most of its time getting the audience trying to guess who Big Mouse is, who in the world is the "invincible" guy who managed to swindle something like 100 billion from crooks in the upper echelon of a shady corporation. The possible suspect moved from person to person, and this was how the drama dragged its feet from Episode 1 until Episode 10. The inanity.

The mayor, Choi Do Ha, turning out to be the big bad was no surprise, it was obvious from the point he sought out Park Chang Ho and got him involved in his quest to retrieve the ever so secretive "scientific paper". CDH's reasons to enlist PCH's help was superficial and illogical, it just didn't make sense to me. Right here and there is a big glaring plothole. There's no such thing as a "secretive scientific paper". Do the writers know that peer research papers go through a lengthy review process and is processed dozens of times before the final publication can be made? There's no way a paper that exposes the hazards of a radioactive substance of that magnitude can be kept secret for so long. It's just ridiculous writing.

Not to mention Hye Jin's murder was unnecessary, and to top it off, her death didn't even serve any purpose other than providing nonsensical shock value to the audience. She escaped to the US only to come back to get murdered. LOL. Why? If I were thousand of kilometres from my psychopathic ex, I wouldn't go back to where he was. Yeah, her ex-husband is worse than scum, and he didn't even get punished for her murder. Her body was never found! This subplot was completely dropped by the writers. For what? Yeah the mayor Choi Do Ha is also scum for helping him dump Hye Jin's body. Then it turned out Choi Do Ha wasn't even Choi Do Ha, he usurped the identity of a dead boy! What in the world. LMAO. Tell me how you do that as a kid. Who helped this kid changed his legal papers? This trope is tired and old, and honestly if people want to pull this in modern storylines, they need to provide a more viable and cogent explanation.

After all the twists and turns this drama flipped out, it was revealed that Big Mouse is really not a single entity. It's one guy, who's the head of some secret organisation, like Freemasonry, but mafia ala vigilante-style, with some dozens of members who abide by a set of organisational "code" - that also wasn't made clear to the watchers. Lmao I don't even know how to describe this circus house - this is the worst drama Lee Jong Suk has ever been in.

There was a scene where Park Chang Ho was tortured in a white chamber - why?! To extract information about the 100 billion dollars he siphoned off - allegedly. After he became Big Mouse, did PCH expend any energy to find this place he was held in, and did he bust it with his newly gained cronies of the Big Mouse organization so as to prevent future abductions and illegal imprisonment? No. And because of that, while we saw that the mayor truly "loved" his wife Joo Hee, in the end he nevertheless subjected her to the same white chamber torture after learning that she had betrayed him. It was just so inconsistent with their characterisations.

Holy crap, I still have so much to go on, but I'm trying to end this review quickly. The loving relationship Park Chang Ho had with his wife Ko Mi Ho was dealt a cruel blow after she was exposed to "radioactive" water. She quickly developed cancer, which progressed to Stage 4, within weeks of exposure. Like?? LOL, that's crazy. First of all, the drama told us NK9 is a highly toxic material that was found in the wastewater of their plant, but we weren't told how toxic it was. We just have to believe that it's super-super toxic, okay? I wonder if the writers came up with this idea from the time Japan announced dumping wastewater from the Fukushima plant into the ocean, which was met by protests and condemnations from Korea and China, but endorsed by the US. Anyway, in real life, allegedly, drinking water with radionuclides in it could take years for harmful effects to show, and yes, that includes an increased risk in cancer like leukemia. But the people in the drama who had contact with this radionuclides-filled water actually developed leukemia and died within weeks after its one and only exposure (Tak Kwang Yeon, Ko Mi Ho)! What's even more hilarious is that Choi Do Ha was eventually killed by the same radioactive water (that looked as clean and clear as your normal chlorinated pool water btw) on the same day he swam in it. Upon being told by Chang Ho that the water was radioactive, Do Ha then crashed into the pool like a plank. LMAO.

So what about the 100 billion that everyone was after in the first place? The 100 billion that placed Park Chang Ho in this predicament he said he didn't want to be in? Where is it? Gone, Soon Tae said. Someone stole it, and that was that. No mention of it ever again. What about the hospital that Joo Hee was serving director at, the hospital that had forced the next-of-kin of their dying patients to sign DNR agreements? Joo Hee had been serving at the hospital as a director, there's no way she was ignorant of all the criminal activities in the hospital. She's very much aware, and her last minute redemption by exposing everything her husband had done gave no closure on whether she was being held accountable for her actions as well. For a massive scandal like that, she would have been imprisoned IRL. I mean, really, what about the rushed cremations of the dead patients, what about the evil head nurse and all the other bitchy nurses who distributed life-threatening pills and injections, masquerading them as flu shots, medicine and vitamins? There was no comeuppance for them. Nothing. So really, what the hell did I just watch?
