Forget all the talk about Ripley, I think the best part of alien 3, although I love the movie completely, was after the prison was locked down, the cryo-pod's computer restates Ripley's sign off speech. (Still, and will always give me goose-bumps.) That should have been the final appearance from Sigourney Weaver, and would have still left her for what she was from the beginning of the series. A strong female hero character, one of the first, that paved the way for other female based heroes in the future. .. But no.. she came back, and the script completely tore her character to shreds. She knows this. This is why she has such a hard time falling back into a role that left her career for dead. In Alien 4, they made Ripley's character far too lost, and tried too hard to show that she was losing her mind.. and the whole, being upset when "her" aliens were killed was again just a little too far for the character we all know her to portray. I for one would love to see an Alien movie stray away from her character, and start along a new path.. The only path at the time that seems the best would be a prequel regarding the "Space Jockeys", {...although they remind me of the bird things from "Metroid" that you would get your powers from}, and how the aliens directly came to be..
