Saw it last night...
...at the NFT and my verdict is.....it's quite good. Not brilliant, but watchable. Some good performances from the mainly young cast, particularly the two leads. Anyone expecting a straight-up 'hooligan' film will be disappointed though. Much like Kevin Sampson's book, the film is essentially a love story set against a backdrop of football violence. The fighting is integral to the plot, but secondary to the relationship between Carty and Elvis.
The Q&A afterwards was interesting, albeit brief. Liam Boyle can certainly talk!
