Joss Whedon has never made his intense dislike for Alien Resurrection a secret, but in pointing the finger elsewhere he overlooks the issues inherent in his own screenplay. The Alien franchise was intended to come to a close with 1992's Alien 3, which went through a notoriously difficult production and ended with the death of Sigourney Weaver's Ripley. Despite the latter's mixed reception, Fox later greenlit another sequel and hired an up-and-coming Joss Whedon to write. His original concept saw Aliens' Newt being resurrected, but during development, the studio requested it focus on a Ripley clone instead.
