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

The story, direction, characters, and writing/dialogue is akin to taking a tranquilizer shot to the neck, but everything else was so well done.

The film never slows down or bores, plunging from one harrowing sequence to the next.

While it doesn't offer any answers, it both thrills and makes you think.
