If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

I have absolutely never seen anything like this movie before. You have to see this movie.

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

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