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

There are moments in this movie where the great movie it could've been peek out... They're fleeting, here, but they're worth savoring, and they happen often enough to make it worth your while.

The film's masterful storytelling did its job. The message was clear. No need to overdo.

The storyline feels a little thin and moth-eaten in parts but this sequel is plenty of fun.
