if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

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

The storyline feels a little thin and moth-eaten in parts but this sequel is plenty of fun.

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