good back-story, and good acting

It isn't all that great, actually. Really cheesy and very predicable of how certain scenes are gonna turn play out. However, I guess that's the charm of it all, because I would consider this one of my guilty pleasures.

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

One of the best movies of the year! Incredible from the beginning to the end.
