Very Cool!!!

Simple and well acted, it has tension enough to knot the stomach.

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

The plot isn't so bad, but the pace of storytelling is too slow which makes people bored. Certain moments are so obvious and unnecessary for the main plot. I would've fast-forwarded those moments if it was an online streaming. The ending looks like implying a sequel, not sure if this movie will get one
