It's no definitive masterpiece but it's damn close.

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

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

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