Blending excellent reporting and strong storytelling, this is a disturbing film truly stranger than fiction

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

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

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