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.

Great story, amazing characters, superb action, enthralling cinematography. Yes, this is something I am glad I spent money on.
