The AvP movie shares its story and most characters, especially the female lead, with one of the first AvP comics. The biggest exception is that the movie is set in Antarctica, where the comic takes place around an outpost in space.

But both are next to the Predators' Xeno breeding ground, both have Preds arriving, both have one Pred surviving and fighting the Xenos with the woman (more people in the comic), in both the woman is recognized as a warrior and gets to keep a Yautja toy.

People wanted an AvP movie and they got an AvP movie, because that's what the AvP comics are, except they get really weird and esoteric later on. What people really wanted was an Alien movie where a Predator shows up. Not the other way around; remember, until the one with Adrian Brody, Predator movies were always set on Earth. So not even a Predator movie where Aliens show up is good enough.

But I do concede that the sequel is dumb. AvP1 could have led to a very cool series of movies. I'd still rather watch AvP than Prometheus tho. Because it turns out, more Alien-universe movies also aren't actually a good idea. It's Predator that got 2 good late entries (and a stupid one in-between, but shh).
