I never had a problem with Alien 3. I think its the only film that ever grew on me in the franchise to like it even more as the series aged.
When I was a kid it was Aliens-Alien-Alien 3
Then it became Alien-Aliens/Alien3. I like it just as well as the second movie, which I think has aged the worst out of the three. It's still great. I just don't think it's as great as I once thought it was.
Alien Res was always too goofy for me. That has been my one consistent problem since I saw it in theaters in 97. Wasn't serious enough.
I remember SciFi had an edit of it back when tv couldn't show all the gore or have all the cussing and it was so much better without all the awkward Perez pulls his brain out and looks at it moments.
Oddly enough, I've still seen Resurrection more times than I've seen most other movies from other franchises.
