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

A movie that not only functions as a solid scarefest but a razor-sharp satire.

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.

Like the great film, it's made with a great deal of visible affection both in front of and behind the camera.
