It's entirely possible that sending the audience out feeling lousy was intentional

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

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

The story-telling is good with flashbacks.The film is both funny and heartbreaking. You smile in a scene and get a soulcrushing revelation in the next.
