I nearly hated Alien 3 first time I saw it. Once I got passed my need for typical sequel-itis, (I also grew as a movie viewer by the time I revisited it), I realized it was incredibly balls in its plot. After disovering Fincher's struggle in making it and the studio's intrusion and original ideas for it, it went up a few more notches. Then I saw the extended/producers/whatever cut.
I love Alien 3, and I would love to hear Fincher discuss it, but I understand why he never will.
