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

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.

Amazing worth wacthing. So good. Biased but well made with many good points.

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