What begins as a feel-good-human-interest story turns into a mystery, then a tragedy, and ultimately an outrage.

Unshakable, witty and deeply felt, the film will be paying emotional dividends for a long, long time.

It's a movie as timely as it is provocative and amazingly, for much of its running time, it is weirdly funny.

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