I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

good back-story, and good acting

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