This film implies it's based on a true story which I think is dishonest. It's loosely "inspired" by a few different notable violent crimes. Presenting it as based-on-a-true-story is a cheap way to make their movie seem more legitimate. The main characters are trashy and uninteresting. No depth. No real emotion. To the reviewer favorably comparing this to Bully and Boys Don't Cry, you are either part of the film crew or completely ignorant when it comes to filmmaking and story telling. This film is somehow managed to be pretensious and trashy at the same time.
