It has always been perfectly clear that Amy is an aberration. She is a woman, but she is not only a woman. She is also a monster, and the second half of Fincher’s film is, in many ways, a horror movie about the great difficulty — and eventually the impossibility — of defeating her. She is the rare monster in a monster movie who wins at the end. Whatever she has to do, however offensive, however distasteful, however horrifying. It is in Amy’s specific, defined character that she will do anything. She is that smart, that angry and that unfettered by conscience. It is not her lack of conscience or her ruthlessness that is gendered; it is the way she expresses those things as a result of her very much gendered life. Amy’s pathology plays out in the fields of marriage and childbirth because that is where she sees herself having a chance to attain power. That’s where the high stakes are, and a person as angry and intelligent as Amy knows how to locate the highest possible stakes.
