I apologize in advance for going off topic but since I went trough a couple statements concerning the cannon I had to get involved. I for one love the Alien quadrilogy+Predator1/2 (with a few nitpicks here and there), consider the first AvP movie as generic at best, dismiss the existence of the sequel which is an abomination, feel disappointed by Prometheus and find Predators for a descent but unmemorable feature. I can't comment on any other source material like the Dark Horse comic series or any AvP/Alien based literature.
