AWESOMENESS AWESOME!! Heart...stop it!! That was GOOD!! I don't know where to begin because I am not going to give anything away. I must say, this is not for the faint of heart. Within the first 10 minutes, you'll be jumping out your skin. As I was watching it, it reminded me so much of Silent Hill (no, I never finished that) but story was reminiscent of it. Lee Si Young was AWESOME in this role as Ji Hyun. I already have mad respect for her but now..She will creep up as being one of my top 10 favorite actresses. Uhm Ki Joon as the Det. Ki Cheol was so brass as the cop who basically continued my negative opinion on Korean police. But his acting was definitely stellar. Give it up to Hyun Woo as Young Soo. As Ki Cheol partner, he handled the role well. But again, not everyone can watch this. There is some seriously twisted and scary scenes in this. From start to finish, you didn't really know where the story was going to take you but that ending. Loved it! I still have goose bumps!
