I've seen better quality films but I didn't think this was too bad. I liked the fact the gangster bits were set around London and not always at a football match (in fact there is no football mentioned in the entire film) and the war stuff was OK but some of it was pointless (walking round a field).
I do enjoy watching low budget films and by reading other people's opinions as well they didn't have much budget so fair play
Acting was good from the main cast, some of the others let it down a bit though.
Gonna give it 7/10 as it did make me laugh a few times with the mask bit and the cab bit and also enjoyed the battle and fights
Would have been better if made with better equipment though
