It's hard to see any effort in the film. There's no comedy to speak of, no real drama and, worst of all.

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

The movie's not perfect, but it sticks the landing of its message. It was engaging - thrilling at times - and I personally thought it was a great time.

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.
