It's alright. I own the DVD and solely like it because of my love for OC flicks. It does progress to fast though, I would've liked to see more emphasis placed on characters like John Scalish, Lips Moceri, and the brute from Danny's crew (who's name escapes me). John Scalish is literally shown in one scene at the beginning before it's announced he died. Moceri wasn't even a major part of the movie, the only Italians who got that shine were Nardi & Licavoli. And the NY scene with Fat Tony really annoyed me, I wanted more.
The best part about this movie, if you own the DVD, is the documentary that comes with it. Now that's good, the cop that grew up with Danny does most of the interviews and gives a good insight, from his view anyway, of who Danny was and what he did for the Irish neighborhood. The Hells Angels scene in the film, is completely true according to the documentary, which in itself is pretty badass.
