Well, I wasn't expecting it to be as violent as it was, but damn it, it was fun as hell and a nice affront to good taste. Very well directed too. Much better than a lot of recent movies with the same concepts. I think it succeeded mainly because it was so violent, it actually satisfied the audience in that regard.
Incidentally, the Daily Mail's article tearing into it is hilarious. I believe the term for it would be 'Completely missing the point'.

Once again, the Daily Mail proves their ability to link absolutely anything to paedophilia, knife crime and Jamie Bolger. Paranoid rubbish, but hilarious.
I love the verdict they give it. "Verdict: Evil"
