First of all, this is not a good or a bad movie. It is a little boring, and a couple of things did not quite match.
However, it has a very serious violence (no action, pure raw and disgusting violence) with enough good taste to avoid blood all over the lenses (but not less shocking), and compared to the Oliver Stone movie, it is a lot better and really delivers the message.
All three main characters are marginal people. One of them a dying drug addict killer, the other two are nobodies trying to find a way in life. I do not think that every lost person in the world could become a killer or a psychopath; but there are not bad candidates either. The concept of TV generating violence, is not new and hardly arguably, but the way it is presented, without any poetry or sympathy makes the point better than any other movie on the subject.
Conclusion; this is not a commercial movie. It is the type of film you see when you are looking for something deep that makes your brain work. Overall, you will probably dislike it, which is a good reason to give it a try.
