after the promising first minute of the movie which look like they where try to build a serious profile behind the killing and the movie drift to a simple and disgust presentation of violence . a movie make for pervert . the acting be decent and the storyline be not . the entire plot focus on the student try to understand the psyche of the killer be only base loosely on the fact and all lead to build up more shot with violence . even so it may have happen that way why would you make a movie that feature the most disgusting thing a human have do . look to me like the director and writer fail to find a clear statement for the film and therefore go down the easy way by produce a flick that thrive on pain and the scandal behind it to get recognition at the box office .
