I can't believe threads like this are still going on. Crazy. Anyways, in my eyes, AVP-r showed the nature of the beasts, not, as in AVP, as more or less killers. The Aliens by themselves are gruesome, violent creatures. You can't inject any part of their life cycle, realistically, and make it rated PG-13. Nor can you do that with Predators. The whole ritualistic murder side of the preds can't be taken lightly, and I believe that the skinning of a human being should call for a higher rating. Though I have found many problems with AVP-R, mostly canon issues, AVP was an extremely sad excuse for an alien/predator film. They took the most important elements (chestbursting, impaling, etc...) and watered it down so that it would cater to a younger audience. I believe that is just sad.
