I would have been disappointed if they had made it as an "R" movie...there is so much that you cannot get away with in an "R" movie that isn't pornographic. Remember, to get an "R" rating, you still need a catholic priest to sign off on it (I wish that was a joke). An "R" rating would not have let them "Harvest" little girls...not even freakish mutant abominations that just happen to look like little girls. Heck, harvesting happened off-screen in the games, and it was still disturbing the first few times...even by my standards (and I killed off every kid I find in Fallout NV).
