Whatever way you look at it, if Ripley's in it, it's a problem.
Either it means retconning A3 out of existence, which despite it's script flaws, is an admirable film that closes Ripley's story very effectively, and doesn't deserve to be dumped on by FOX.
Or it's the continuing story of Ripley 8, who was a uninteresting character in a terrible film.
Why saddle yourself with such problems?
