I really wanted to like this movie. I feel terribly cynical trashing it, and that's why I'm giving it a middling 5. Actually, I'm giving it a 5 because there were some superb performances.

A film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.

Yes, absolutely, there is fun to be had, as well as many, many things to go boom, all amid an atmospheric urban jungle.

It's easily one of the freshest, sharpest and most enjoyable films of this year.
