This Is England -
Wasn't expecting much from this film, but was very pleasantly surprised.
The reviews did pick up the flaws in it, however, they also called out that it rose above those mistakes to stake its claim as a seriously good film.
Wins bonus points from me for decent Northern accents (although I'm Lancashire rather than Yorkshire), but mainly for managing to genuinely portray a believable understanding of where skinheads came from and how someone might become a part of them.
It's not a sympathetic portrayal, but it does have a crack at understanding it.
Moreover, Stephen Graham's performance is dangerously brilliant, it's possibly the best "insane" characterisation I've ever seen.
Seek out British films everyone, we're really quite good at it!
