I watched this with a group of friends as part of a horror movie double feature. The first movie we watched was Cabin in the Woods and we all loved that one and were wondering how we were going to follow it up. XBMC (X Box Media Center, great way to organize your media in a visually pleasing manner) had this in the horror genre and had it rated higher than Cabin in the Woods and The Thing from 1982. While my collection of horror is not the most complete, it has some pretty good movies in it and having this as highest rated was intriging, so we all decided this would be the second movie. We were not disappointed.
The story is a simple revenge plot. Kim (Lee) is after the serial killer that killed his wife (Choi). The story does take some twists and turns along the way.
The acting was excellent. Korea is very good for comedies as the actors tend to over emote, but there was none of that here. The acors brought the weight into the performance that it deserved. We attempted to watch it with English language dubs, but quickly changed our mind. Watch this one in Korean with subtitles. The English language dub is horrible.
Overall, it was a great movie. Not sure it was horror unless you consider man as the scariest monster their is. I do. It is our twisted minds that created all these monsters in the first place. The only problem seemed to be the ability of the characters to recover from harm. 20 bashes to the skull with a metal pipe is going to kill anyone on Earth. Maybe he should have worked the body with most of those strikes. If you liked Silence of the Lambs and Taken, this one should be great for you. I have heard it compared to Oldboy, but I still haven't seen Oldboy. I don't think kids are ready for this one. It was almost a 19+ in Korea.
