Well if you're going to make an alternate sequel to Aliens and do it the right way, it's going to retain the elements of Aliens while further expanding the world, just as Aliens did with Alien. Aliens takes from Alien, Alien 3.2 takes from Aliens AND Alien but by taking from Aliens it's taking from Alien anyway.
Yeah, y'know, we like action, horror, and sci-fi around here. Widen the circle each time. A sincere Alien 3 would have given us: space jockeys, Weyland headquarters, a Weyland character, more locations, pulse rifles, action, horror, suspense, adult Newt & Bishop & older Ripley and Hicks.
Doesn't mean it's a clone of Aliens anymore than The Dark Knight Rises was a clone of The Dark Knight or The Bourne Ultimatum was a clone of The Bourne Supremacy or any third was a clone of the second.
You ain't ever had it so good until Aliens! Seven Oscar nominations, boy! Stop kidding yourselves.
