Story: It's very simple but honestly that is fine.

One of the most extraordinary films you will see this year. Take that as you want.

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

Watching it is like watching the spectacle of a class clown at their best: you laugh at their jokes, instigate their defiance, and "ooooh" when they get in trouble.
