Been done, and much better

Rating: 3/10 (25 January 2005)

Coming out about 15 years too late, Alien vs. Predator gives us a skeletal version of a concept we've actually seen already. If you were the type to care at all about Aliens fighting Predators, then you've already read the comic, played the game, or written your own fanfic about it. The big-screen version adds little to the tired mythologies of both franchises, and any attempts at trying make the conflict work in both universes -- like the revelation that Predators have influenced human development -- come across as pure cheese.
Not to mention it's sloppy. The modern-day setting isn't used at all (at times, it even feels like it's set in the Alien-universe future, even though it's not). Fans of either franchise will fret at the tons of retcon, including the Predators-as-gods crap and very short Alien gestation times (except for the last one, which is never explained). There's also a notable goof where not one of the humans exploring the "sacrificial chamber" seems to notice the extremely large, fang-filled skull lying on one of the "beds." This doesn't even match up with the flashbacks that show humans, not Predators, being sacrificed to breed Aliens.
AvP: A very poor realization of something that was once considered a cool concept.
