Remember to be ready for one of the most violent and intense movies you've ever seen before watching this uniquely gruesome movie. The movie is surely not for the faint hearted . I had to pause the rolling for some time and take some are after a lot of scenes on this film . And don't think that it gets any easier watching the film after the first time. On the contrary , after watching the movie for the second and third time, you feel it gets more intense because you can feel every bit of acting and the great believable cinematography along with the masterful directing of the movie. There maybe many Korean movies about revenge but this one surely stands out the way Old boy or sympathy for mr vengeance did back then.
