Tells a fascinating and unsettling true story, and does so well, without pretending to have all the answers.

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."

Excellent characters with emotional depth. My wife, daughter and granddaughter all enjoyed it...and me, too! Very good movie! You won't be disappointed.

If you're interested in the topic at hand, you should just watch it and judge yourself because the reviews have gone very biased by people that didn't even watch it and just hate (or love) the creator. I liked it, it was well written, narrated, and directed and it was about a topic that interests me.
