This movie isn't for the faint-hearted, but if you are into this genre (demons/possession/horror/gore) you will love this movie! Since it's a movie, and not a drama, it's fast-paced and exciting. The special effects were great too; lots of demonic action, with lots of blood! LOL, I love horror. The two leads, Kim Yeon Seok and Kang Dong Won, really did a great job with their acting! Highly recommend! (Kind of swooning a bit over Kang Dong Won; he's not a pretty boy, but there's just something about him...)
