Taking inspiration from the works of Joel and Ethan Coen (hints of 2007's " No Country for Old Men " are unmistakable), Rob Zombie (the guns-blasting third-act skirmish resembles 2005's " The Devil's Rejects ") and Eli Roth (the very plot is but a religious-themed variation on 2006's " Hostel "), the film ultimately averts genre expectations, starting off as a raunchy teen comedy, moving into ghastly horror territory, detouring into a bullets-whizzing action pic, and concluding with a perfect satiric exclamation point.
Sadly, that doesn’t happen: Smith shies away from the tantalizing development and the story comes to a much more traditional close, obviously inspired by the end of No Country for Old Men.
