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

Unshakable, witty and deeply felt, the film will be paying emotional dividends for a long, long time.

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

This is ultimately a movie about the very bad things that can happen when we don't address our unease, when we just try to brush it off, whether that's to fit in or to preserve our self-image.
