Ok, so one more before I close up shop for the night. Incidentally, have you noticed that the focal character in each Alien movie is a woman? That makes it rather unique in a male dominated genre. When I was in college, the one unforgivable sin was not inviting the our female friends over for an Alien marathon.
So, Ripley, Shaw, Daniels... Why is it always a woman? Is it a matter of "give me the same thing... but different"? Is it that images of motherhood and birth dominate the dark language of the films? Does one necessitate the other? Given Alien's roots in H.P. Lovecraft's fiction, the choice to consistently move away from an academic, male, hero is a decisive one. It's given us some great characters and a great string of movies (I leave the exceptions up to you).
