AVP was a bad idea right from the beginning, and trying to convert the travesty onto the silver screen was, is, and will forever be, a mistake. On the drawing board Aliens vs. Predators sounds like a great idea, but it's just superficial. Knee-deep nonsense. Keep em' separated (...except for a AVP game here and there... just saying... sometimes you just want to duke it out, claws & wrist blades, preferably with a paltry marine stuck in between).
