So, and forgive me because it's been a hot minute since i've re-read these books, while the SETTING of AVP the book and movie differ a lot of the same beats are hit ( https://en.wikipedia.org/wiki/Aliens_vs._Predator_(novel_series) ) down to being marked by the Predator as one of theirs. The big part that changed in the ending is that in AVP the movie the predators are just like like...peace out homie, and in the book she's taken to the homeworld where basically she's treated like shit because...well racism.
Now Alien...Resurrection I believe *fact checks self* pulls HEAVILY from this trilogy ( https://en.wikipedia.org/wiki/Aliens:_Nightmare_Asylum ) . Billie, why is Ripley alive, all that stuff is from that trilogy which is pretty awesome - thing is...that's actually a really good trilogy - that movie was hot garbage.
That's what I mean with the movies play with book elements. They cherry pick what they want to take from them without actually making quality films based on those works. Yeah a movie about the predator homeworld, where a human is just trying to fit in would be boring to anyone that's not me but you got to learn their culture. The Yautja for the most part are represented pretty well, it gets a little cringy when shit like predator dogs get involved and...I guess for reasons, you can't really get into the "blooding" ceremony too much (basically the plot of AvP at any given point) because that's just too much crossover.
