Where I come from, this film is known as Green Street, and there are four main reasons to watch it:
1. Elijah Wood gets punched in the face a lot.
2. Charlie Hunnam is a powerhouse.
3. Completely over the top cockney accents: "ee's a JEEERNO!"
4. 'ALLO BOYS!
In all seriousness, this is a good film. I did start to feel some sort of attachment to the characters half way through it, despite the fact that they were all scum. Although there is some glorification of football violence, this film ultimately points out that the way of life of a football hooligan is utterly pointless and wasteful.
