With Ma Dong Seok as the main lead, not gonna lie, my expectations soared. And while I wasn't let down, I couldn't shake the feeling that there was so much more story to tell. A movie just didn't seem like enough; this tale deserved for a longer format, perhaps a 6 to 8 episode series, to truly dive into its depths.

I personally felt that the movie missed an opportunity to delve deeper into the aftermath of the earthquake, exploring the lives of the people affected and shedding more light on why the doctor descended into madness. The three-year time jump after the earthquake left me wanting more— craving a more thorough exploration of the characters' journeys.

Additionally, the movie could also have expanded on the mad doctor's research, providing a more detailed and scientifically grounded explanation for his actions. Perhaps I also missed a crucial detail, but I found myself confused about the significance of the laceration or whatever it was on the back of their ears. I think more explanation or context around this detail would have been helpful in understanding its importance to the story.

The part when they discussed the mission to rescue the girl, I couldn't help but anticipate one epic journey ahead. Yet, it felt a tad too short-lived. The irony wasn't lost on me when the military woman emphasized the tight security at the apartment, only for the team to effortlessly breach the building, adding a humorous twist to the situation.

Despite its brevity, I thoroughly enjoyed watching this movie. And of course, action-wise, Ma Dong Seok always delivers, never failing to captivate the audience with his prowess on screen.
