Let's be realistic.

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

The biggest problem with this movie is it’s a little better than you think it might be, which somehow makes it worse. As in, it takes itself a bit too seriously, which makes most of the movie feel kind of dull.

The film never slows down or bores, plunging from one harrowing sequence to the next.
