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."

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

By the time the dramatic fireworks start popping off, each one feels earned.
