Pretty good movie overall. First half was nothing special but it got better as it went along.

Tells a fascinating and unsettling true story, and does so well, without pretending to have all the answers.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

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