Something no one seems to understand about "screwed up the series"
A lot of tools here (not everyone, A.Nightmare and SM) seem to think that the story and art direction are why the directors are so pissed. Its about the style of movie, and the respect of the film community.
Before: "The Alien series is an intense horror sereis"
Now: "Yeah, they started good, but now....."
Face it, the series is living in its past, as well as Predator, which unfortunately only has one good film to dwell on.
AvP is ruining the Alien franchise in ways not done yet by A3 or Res. Yes, those two f**ked up the story canon, but at least they kept the franchise true to its purpose: to be scary. The Aliens were still icons of fear and suspence, and even a little mystery. They were genetically horrifying and incomprehensible on many levels. They were alien to the audience. And yes, Aliens may have more action than Alien, but it was still horror/suspence to its core.
AvP has taken away the horror. Was anyone scared? No. My sister, being very squeamish, was freaked out by everything the original movies had to offer (even Alien Res and A3!) But even she smiled at AvP's lame suspense.
It changed the whole genre of the franchise, even that of Predator. It made Aliens action creatures. They were weak, stupid, and more semblant (in behavior) to the Arachnids of a very dissappointing Starship Troopers. The Aliens were always fully exposed on camera, never hidden, never sneaking. They simply ran around flayling arms and screaming.
AvP took the Aliens out of Horror, and then took the horror out of Aliens.
