Just too many incidents of violence.
The film goes from one scene to another, and in nearly every one violence erupts.
Now I am not one who is shocked by violence, and to me a film without a fight in it has something missing. But, please, not one after another. My reaction was not shock or horror, it was: "Here we go again." There is some semblance of a story in between the scenes of violence, but two thirds of the way through the film I had switched off completely, and couldn't wait for the end.
If this is the best the film makers can do, they should find something else to do with their miserable lives, like making shoes or delivering mail.
