This is a must-see and one of the best documentaries - and films - of this year.

Go in cold, and you're likely to emerge with your blood boiling. This has to be seen to be believed.

Great example of an old-fashioned, pure-at-heart escapist event movie that doesn't pretend to be anything that it's not and has boat loads of fun being its own ludicrous self.

After playing with our expectations, this turns out to be a very different sort of film.
