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

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

Exactly the movie you think it is, but not the movie you want it to be.

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.
