As I said above,
I feel that A3 and to a greater extent A:R have hurt the franchise more than any "retcon" could, and at this point a retcon(or at least "resetting") of the story could reinvigorate it. Again, it doesnt have to be a movie similar to ALIENS, just use ALIENS as a jumping off point bc I feel there is more potential to a story there than at the end of A:R. I just really HATE Ripley 8, sorry. Plus, continuing from A:R would have to acknowledge all the events in A:R, which are just so stupid and goofy/corny. The only good thing A:R did right, was set itself 200 years after the trilogy so at least its so far removed from the first 3 that its easy to ignore/dismiss. Continuing from A:R would just dilute and hurt the Alien continuity storyline even worse.
