The twist was surprisingly enough completely (okay maybe not completely but at least moderately) unexpected, but it was all so horribly bad that it didn't make up for shit. You'd expect a movie released in the year of 2012 to at least have decent visuals and alright acting even if the whole story and setup is as dumb as it can get, but nooope they had to make that complete and utter crap too.
I'd rate this two turkeys out of five, for being up to standard with what was expected of it.
