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.

Yes, absolutely, there is fun to be had, as well as many, many things to go boom, all amid an atmospheric urban jungle.

A film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.
