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

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.

There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
