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

Unshakable, witty and deeply felt, the film will be paying emotional dividends for a long, long time.

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

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?
