To me, the Alien movies stopped at #3, and I barely liked #3 but it was interesting.
Dumbest thing in Sci-Fi... an alien, an armored alien at that, gets sucked out into space, through a BULLET HOLE. Never mind that you could simply plug up that hole with the palm of your hand.. noooo, they spaghetti-fied poor sad Mr Alien into space...
IMHO, Alien Resurrection is on a par with "Wing Commander" and "Highlander II" (there should have been only one) in the annals of Sci-Fi movie badness.
