If you don't like this, we can't be friends.

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

The joyful confection is coated in a sparkly gloss, bright enough to gleam from the darkest, most cynical corners.

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