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."

It's easily one of the freshest, sharpest and most enjoyable films of this year.

It is encouraging that the film ends so strongly.Otherwise, it wouldn't have been a particularly memorable film
