It's not great by any means, but it's a pretty good movie that didn't leave me filled with regret for investing time in it.

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.

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

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.
