Sadly Over-hyped

This is a must-see and one of the best documentaries - and films - of this year.

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.

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