Blending excellent reporting and strong storytelling, this is a disturbing film truly stranger than fiction

A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

One of the best movies of the year! Incredible from the beginning to the end.

One of those movie experiences that is so good it makes you realize you've been grading everything else on a curve.
