At first rather annoying in its heavy emphasis on reenactments, this movie ultimately proves fascinating, simply because the complicated, highly dramatic tale it tells still almost defies belief.

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."

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

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
