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

Unshakable, witty and deeply felt, the film will be paying emotional dividends for a long, long time.

The acting is good, and the firecracker script has some excellent ideas.

This is a coming of age storyline that you've seen in one form or another for decades. It takes a truly unique voice to make yet another one worth watching.
