I guess most of the people who reviewed the movie, didn't like Bushido. I can only guess that most of them thought he was full of himself. Maybe that comes down to the fact, that his acting isn't really up to the task. And it's most unfortunate, though I'm not sure why the director would want to cast him in the movie, if he saw any sort of test screening/performance of Bushido.
Bushido on the other hand is best, when he is singing. You can feel his energy and power when he performs. Unlucky us, we don't get to see him that often in that "mode". When he is talking about his life or things happening, it sounds like he was forced to read something of a paper and trying to get back at the people who forced them, by not putting any emotion into the reading at all.
Not everything will have happened as told here (I'm assuming, especially the very "dramatic" ending) and this will mostly appeal to fans ... I don't think he will gain new fans, with the movie ... But decide for yourself if you're brave enough
