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

The movie's neither hopeful in contrived ways, nor hopeless in different contrived ways. Somehow it manages to be wonderful

This movie feels like it was made purely to piss off people who want good shows

The joyful confection is coated in a sparkly gloss, bright enough to gleam from the darkest, most cynical corners.
