That is the exact opposite of Uwe Boll haters. They bad mouth his movies before they have even seen them. I think it was Uwe Boll himself that said in an interview that on IMDb they had over 500 votes for his Bloodrayne movie [before it even came out] and all of them were a 1. Those that hate him so much are not real movie buRAB. I agree with what you said: they will be prepared to watch anything at least once over. Then they can decide if it is good or not. Otherwise they talk through their arse as they don't know what they are on about. Not saying that I support Uwe Boll or anything, but still, one can't help but notice the idiots that jump on the bandwagon of hate for him, just for the sake of it.
As for this movie, well all I liked about it was the small tribute or rather piss take for Grand Theft Auto: San Andreas. That was the stand out part of the movie in my view.
