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.

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.

The best films of this genre always show a path and provide a takeaway for being a better person.
