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

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

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.

The film never slows down or bores, plunging from one harrowing sequence to the next.
