Writers ALWAYS, ALWAYS over exaggerate on how gory their work is. They always think they're superior to others with gore standard, when in reality they're fairly tame. (Remember M. Night's comments about The Happening being rated X? Ha! That movie was PG-13 all the way!) I've yet to see a Greg McLean movie that was even close to the level of violence in your standard horror movie, much less above and beyond it. Wolf Creek was fairly brutal, but it did nothing on the gore/violence/graphicness scale at all. Rouge was pretty much PG if they had taken out a few f-words. So, really, I don't think Wolf Creek 2 will be much gorier than your standard movie. If Greg McLean does make the bloodbath he's alluding to, I'll be as happy as hell. But I know he won't.
