This isn't a movie that is suited for everyone. The story is really unique in the Korean movie business. I personaly have seen many American ones about exorcism but never one in Korean, so I really liked that. It gives you from start untill end a myserious vibe. The dark themes, the buildings and actors helped greatly in giving off this creepy feeling. But, I wish they didn't threw in some unessecary things (the past of Choi & Kim VS. rest of the fathers). The could have threw it in there, but they should have build more development around those extra side stories, so I am quite dissapointed in that. The cast was splendid, I love Kang Dong Won's work and Park So Dam is alsy a great actress, she can fill in any type of role in a movie! Even though the action is in the last 40 minutes of the movie the actors keep you interested. The music really fitted the 'exocrism' theme, so this also helped building up tension in this movie. Watch this if you like exorcism and a bit gory movie. Skip this if you expect romance and full on action.
