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

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

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

This is a small, humorous movie in some ways, but it has a huge heart. What a nice experience.
