What a strange movie. So dark and bloody but most of it was silly because of Bok Sun. As always Kim Go Eun is fantastic and so was Ahn Seo Hyun.  Kim can cry so realistically, coupled with her character's personality, I think she really shined here. The guy who played the killer, Lee Min Kee, woah! did he do good. So creepy and psychotic! My heart was racing in fear whenever he was chasing them, he's just nuts! Am I crazy because I kinda feel bad for him? It's the classic case of if his family were different, maybe he would've turned out better. I did feel like the story dragged on a little bit and I wanted to fast forward a few times. But it was worth the watch.
