Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

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."

It's simply great fun, a winsome film and an occasionally over-the-top luxury fantasy that never flags.
