This movie was short when compared to other Korean movies I have watched. It was, also, sort of a spontaneous kind of watch since I hadn't planned on watching it just yet. I'm going to go straight to the point not because I hated it since I was totally immersed in its story, but because there's really not much to say. Murderer has an overused premise, but one I enjoy most of the time. I love this type of psychological thrillers. The atmosphere was tense throughout the whole movie even when Yong Ho and Ji Soo were together trying to be kids. Ma Dong Seok, whom I had previously seen in a few dramas, was great as in this off kilter type of character. He definitely exuded danger. Even when I was not the one where his gaze was directed at, I could almost shiver. I hope he does more serious roles like this one. Also, Ahn Do Kyu (whom I remember from "Horse Doctor") is one we need to keeps tabs on. He has the makings of a great actor. I can't say much more without it being a spoiler. BUT, for me, whatever happened definitely clicked with the rest of the story. I do wish they had showed more of what happened after that messed up ending. Messed up because of what happened not because it was bad.
