This movie was really bad. If you enjoy watching a foul mouthed, chain smoking, violent, self important junkie, then you might find this enjoyable. I found it a revolting attack on the eyes and ears. And how did Ewan McGregor get roped into doing this? Roles must be getting mighty hard to come by these days. There were a LOT of better black musicians who would be worthy of a biopic. Like Robert Johnson, Blind Blake, Blind Willie McTell, Blind Lemon Jefferson, Big Bill Broozy or Blind Willie Johnson. But, no, Cheadle had to make one of an angry trumpet player who was mad at the world. And he wasn't even that great of a trumpet player. Herb Alpert is hands down a much more talented player.
