This is an astonishing documentary that will wring your heart while it bends your mind

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

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

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.
