First of all, english isn't my mother language, but i hope everyone at least know what I mean. I think nowadays, almost all tv shows which have good ratings, just part of hype, in fact not all of them is really good. After watching 2 ep, this show is pure action, and i quickly noticed something is off, which is, the logical action of the character based on situation. Enter Lee eun-hyuk. This guy shares a room with his sister. One night, he told her he was going to work. At ground level, he found some occupants grouping together & they seem can't get out. Then a monster attack. Tell me, in your logic, what should the guy do? First he tries to help others to fend off the monster & close the door. Pretty logical. Then he groups up with other. He forbids anyone opening the door to leave. Ok. He goes to security room and watches the monitors. He sits there with others & planning what to do. Errr...wait, did you say he has a sister?
Yep, that's exactly why i told you something is off with this tv show. The character doesn't act logically enough. Does he forget he has a sister up there? And when her sister finally goes downfloor, he just hands her a shirt for cover. No talk. Nothing.
