Besides the poor production and dragging story line... It started out anti-nigger/immigrant.... But then 2 out of 3 "bad guys" on the bus were White. Then later some White dudes drug some women at a night club. Then there is a long, unnecessary sex scene as degenerate as anything to come out of Hollyjewood.
I turned it off half way through. IMO, I would not bother.
That ruined the whole thing more than anything. He's supposed to be an "everyman" character, but he's actually a millionaire with no real stress in life. Nothing he does is any sacrifice or danger to himself. It's not like he decided to quit his job to get vengeance; or struggle to keep his day job while being a vigilante at night. There's nothing there for the target audience to relate to on a basic level.
Also, he's an American in Europe, so it's not like he's tied to the land or even the city. Why does he care? Why do all that in Europe rather than in America? Boll doesn't care and likely never thought about any of these things. The whole movie is cheap bait to capitalize on the public's obvious frustration with the rapefugee invasion of Europe. Boll doesn't deserve one dime or dollar for that kind of slop.
