I don't know about that one. I'd say they're about equal as far as scripts go, neither one all that rivetting, pretty basic and just enough to give a monster movie some substance.
Other than Lance Henricksen, who didn't have that much overall screen time, the acting was pretty mediocre in AVP and about the same in AVPR; I can't watch either and think yes these people are better at acting than the people in the other movie.
This point is a matter of preference. For me, AVPR had better scenerey because the woods and sewers and the nuclear plant and even the hospital all had the primitive and raw feel the environments of the early films in each franchise had which was nice. The pyramid thing was kinda neat, but to me, it felt forced. I've never followed the franchises outside of the films, so seeing the Predators create a pyramid on earth and all just felt too forced to justify the story.
gave the alien creature itself alot more justice
This point really depends on your mindset when viewing the movie; if you're looking to see a balance of Aliens and Predators because of the title or whatever, ya, you'll favor AVP over AVPR all day long. If you watch AVPR either not caring how much or little time is given to each species and just take what you're given, or if you're looking at it more like it's Predator 3, then there's nothing wrong with how AVPR handled the different species. AVPR is a lot like ALIENS, the core of the story isn't about the xenomorph species, they're only there to create a threat and task for the main focal character(s) of the story, which in ALIENS were the marines and in AVPR is Wolf.
All avp:r had was an awesome pred and a pretty cool new creature design with the predalien.
To me, all AVP had was some new style Predators, another variation of the xenomorph and a unique locale unlike anything in the previous films. Not saying AVPR had more, just saying I think they both offer about the same ammount of things and types of things to an audience.
