There is so much wrong with this movie I really don't know where to start. Okay, I do - with the beginning.
The characters are obnoxious, the premise is ridiculous, there is as much depth to the hunted characters as there is to a sheet of paper, and there's no scene setting, no preamble, no build up, and no possibility of investment.
Within a few minutes the plot leaves you in no doubt this is all about showing gratuitous violence without justification, apart from the moments where it's unclear whether the film is a comedy or not. Yes, some scenes are THAT bad.
Don't waste your life watching this, it's utter ****.
