It's not great by any means, but it's a pretty good movie that didn't leave me filled with regret for investing time in it.

If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

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."
