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."

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

The acting is good, and the firecracker script has some excellent ideas.
