People falling over themselves to heap praise on the film gush about it tackling 'difficult issues' etc etc.
Problem: any figures you care to look at will tell you that the majority of gangs in London are black (90% according to some sources) with the second largest percentage being southern Asian. So what percentage does that leave for white gangs? Not much, so you've guessed it (or seen it) the gang in Caine's film are white.
So there's still one 'difficult issue' that this so called brave film is unwilling to tackle.
