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.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
