This movie is no doubt a great thriller. It gets your heart pumping and your palms sweating. This movie keeps you on the edge of your seat the entire time. So why didn't I give it a higher rating? The plot and cast did a great job of delivering a supernatural, crime story, but there where multiple parts where I found myself confused because of the behavior of the characters or unanswered questions. Plot~ Overall I loved the plot! If I had to rate the beginning I would give it a 10. My rating only started to drop once they introduced certain people, and certain events happened. By the end my score was a 7-7.5. The ending felt unsatisfying. There were certain characters introduced earlier on that just disappeared. We have no idea what happened to them. The only person we see at the ending is 1 of the main characters. Basically other than him we have no idea what happened to every one else. They left a lot of things up in the air. This is the part that bothered me. Characters~ Kim Kang Woo did a great job portraying his character, but sometimes I wanted to smack the crap out of him. For a cop he lacked common sense. Some of the things he did were questionable, and at certain times I was sure he idiot. He lets his emotions drive him a LOT, and for a man who has been a cop for years, that made me wonder. How has he survived this long? Kim Bum looked very dark, and very cute in his role! The only complaint I had is that for a guy who's always bleeding and coughing up blood he never goes to the hospital. The other characters such as the other detectives, and Kang Woo's superiors got on my nerves. They didn't act according to their job title, and they were always looking for ways to push the blame, and not accept responsibility. As first I thought they were relatable, but after a while I became confused. How can I relate to men that obviously don't know how to do their job? And who would go to these guys for help? All they care is about themselves! Overall~ Would I re-watch this? No. It was good, but it was definitely a one-time watch. This is one of those movies where the suspense plays a big part. After you've watched it, it just doesn't have the same feeling. Would I recommend this? Yes! It's a great movie, and I think anybody that enjoys thrillers or detective movies would agree that this is one of the best. I wish they had ended it better and given more detail but overall it was an enjoyable watch. Read this review and more at: http://lovekoreana.blogspot.com/
