I am only giving this movie a 1 for the great cast, though I can't imagine what any of them were thinking. This movie was horrible

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."

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

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.
