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.

By the time the dramatic fireworks start popping off, each one feels earned.

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