In truth, there is barely enough story here to make a film.

The story-telling is good with flashbacks.The film is both funny and heartbreaking. You smile in a scene and get a soulcrushing revelation in the next.

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

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.
