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.

Plot so thin, it passes unnoticed.

Tells a fascinating and unsettling true story, and does so well, without pretending to have all the answers.

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