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

This is ultimately a movie about the very bad things that can happen when we don't address our unease, when we just try to brush it off, whether that's to fit in or to preserve our self-image.

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

It is encouraging that the film ends so strongly.Otherwise, it wouldn't have been a particularly memorable film
