good back-story, and good acting

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

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

Very good movie overall, highly recommended. Most of the negative reviews don't have any merit and are all pollitically based. Give this movie a chance at least, and it might give you a different perspective.
