More refined, contemplative, and formally inventive than Prometheus, and smoothed over with a gooey layer of sci-fi schlock right out of the early 50s. It's essentially Paul W.S. Anderson's The Thing From Another World; talkative, haunted by strange, triangular corridors and circular depths, and completely understanding of its own premise. Part H.P. Lovecraft, viscid horror, and 80s team-up videogame showdown, Alien vs. Predator flies past its own genre foundations as soon as it can, instead choosing to unleash stock (although memorable and never annoying) characters into macabre interiors festering with creatures and creepy crawlies. It's a blast from beginning to end, divulging fanboy dreams and playing with iconography while still remaining spooky and tangible (there's a flurry of practical effects here and they're all wonderful). Not quite my favorite W.S. Anderson film, but it's damn close. Practically an "At the Mountains of Madness" buddy picture. Flares and predators and facehuggers, oh my!
