I thought the preview was better than the actual film. The documentary lacks any narration and ends up being an endless stream of clips from interviews with tough guys (oh and Jay Baruchel has a lot to say though I have no idea what makes him an authority on the subject). The story drags on far too long (this could/should be a one hour film!) and the constant footage of fights gets a bit tiresome, if not gruesome, over time. I played hockey my whole life and still struggle with the role of fighting in the game. I was looking for some stimulative thought in this contentious issue but didn't get any from this film. It is very biased, effectively glorifying the enforcers of the game (albeit in a rather covert way). I didnt watch a film on fighters without expecting to see some good fights, but at the end of the day this film lacked any balance or thought provoking ideas about the issue. Just more of a celebration of violence and a subtle resentment of how the game has changed over time.
