Yeah, Predator 2 was certainly no were near as good as Predator, but Alien3 and Alien:Resurrection were both horrid perversions of an excellent storyline set up by Alien and Aliens. An Alien vs Predator movie would work IMO much better than this Freddy Vs Jason movie, because the flick would be dealing with species rather than individuals. But there would need to be a couple things to make it work...
*It should not be called "Aliens vs. Predator". That just sounds dumb.
*It would need a competent director.
*It would need an excellent script.
*NO HYBRID ALIEN GARBAGE.
*NO CHEEZY COMIC-INVENTED PREDATOR "HONOR CODE". The Predator needs to be taken back to its sadistic roots.
*Aliens and Predator(s) that tend toward the design and behavior of the creatures from Alien, Aliens, and Predator (The weapons from Predator2 kicked @ss though).
*Colonial Marines, baby!
