Rating: 7/10 (11 October 2014)

There is no better word other than disturbing which can summarize this movie. The movie is not a masterpiece, it may be because I watched the subbed version of the Korean movie but really the film seems to be unintentionally disturbing at times. The climax takes the cherry. The screenplay makes the movie what it is but I found a lot of glitches in the movie.. The movie is surely not well directed because it feels absurd when the person is searching for the truth and I am unable to decipher what is happening. New characters are introduced without giving clear introduction to them. There is a fight sequence where the lead actor has a fight with some 10-12 odd guys.. That is the worst scene, I mean it was so out of the movie, it felt like he wanted to show us a fight and just dragged that part. Music is not up to the mark, and in the music which is played when the movie opens is pathetic, it does not even go with what is happening. The person(Oh-Dae-Su) is tortured to ultimate level which is the best thing in the movie and is very disturbing but the story telling was good but it missed severely in direction department. Many scenes were over directed.
So there it is as a whole you would find the movie very disturbing but worth the movie for a one time view.
