I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

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

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