Personally, my problem with AvP wasn't Anderson - I kinda liked his other movies and I had hoped he'd do a good job. But as it turned out, he just wanted to use the franchise to get his ridicious super-pyramid theories into a movie. Every single pitch for the AvP movie prior to Anderson were in space, in the future, because you can't just let Aliens loose on Earth. It just ain't right. But oh, no, according to Anderson, they've been here for thousands of years, along with our super awesome Predator overlords. Surely you can't be in favor of the AvP movie - even in the context of the Yautja and blooding stuff from Prey it's all wrong. Scar blooded himself, Lex was an insultingly watered down version of Machiko, and the Predators themselves were reduced to Stargate characters.
I may have my own ideas about the origins of the Aliens and Predators, but that's a good thing - that's the kind of creativity that their kind of mysterious, open-ended stories promote. Even though I think the word Yautja sounds kinda dumb and I think hogtying the Aliens and the Predators so closely together takes away from both's coolness, I'm still okay with all Perry's business. At the end of the day, it was a good story. The AvP movie is just silliness.
Besides, after Alien3, Alien:R, and AvP, this community is an oft-abuse group, repeatedly smacked around by Fox as they exploit our love of these franchises for a cheap buck.
