I finished watching this last night. I'd had this dirty urge to see the movie again. And I liked it. To be honest, I wanted to watch it because of the new DH Press books. Their portrayal of the Aliens is a straight continuation of how they are in this movie - intelligent animals - and it made me want to watch the film again.
And I think it was about time I did watch it again. AvP has made my apprication of the film go up. Sure, the last act and a bit still suck ass, but the first half of the movie is pretty damn good. The characters are interesting, the stuff with the Aliens is interesting. Sure, the Eggs are pretty shitty but the animal design for the Aliens fits their portrayal.
I still hate the set design and lighting though, but the camera work is pretty damn good.
