I cannot think of one single thing that I would change about this film. The acting is incomparable, the directing deft, and the writing poignantly brilliant.

Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

A movie that not only functions as a solid scarefest but a razor-sharp satire.

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.
