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."

The film's masterful storytelling did its job. The message was clear. No need to overdo.

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.
