Although this movie did not get good reviews, it is one of my personal favorites. It has some slow scenes, but the flashbacks are interesting and drive the plot well. Also, instead of getting a definite reason, the audience is left to find the 'why' themselves throughout the film. Language is extremely strong, and there are quite a few references to sexual stuff. Drugs are also used. Disturbing violence is implied, but never shown onscreen. (except for the aftermath). Great movie and I do recommend it!
