In an interesting review of the execrable Twilight series for The Atlantic, Caitlin Flanagan suggests that a major factor in the series’ popularity with teenage girls is the unique dynamic between Bella, the female protagonist, and her love interest Edward, who inconveniently happens to be a vampire. Flanagan writes,
Twilight centers on a boy who loves a girl so much that he refuses to defile her, and on a girl who loves him so dearly that she is desperate for him to do just that, even if the wages of the act are expulsion from her family and from everything she has ever known. We haven’t seen that tale in a girls’ book in a very long time. And it’s selling through the roof. […]
As he gradually explains, Edward has been avoiding and scorning Bella not because he loathes her but because he is so carnally attracted to her that he cannot trust himself to be around her for even a moment. The mere scent of her hair is powerful enough that he is in a constant struggle to avoid taking—and thereby destroying—her. […]
The erotic relationship between Bella and Edward is what makes this book—and the series—so riveting to its female readers. There is no question about the exact nature of the physical act that looms over them. Either they will do it or they won’t, and afterward everything will change for Bella, although not for Edward. Nor is the act one that might result in an equal giving and receiving of pleasure. If Edward fails—even once—in his great exercise in restraint, he will do what the boys in the old pregnancy-scare books did to their girlfriends: he will ruin her. More exactly, he will destroy her, ripping her away from the world of the living and bringing her into the realm of the undead. […] In the course of the four books, Bella will be repeatedly tempted—to have sex outside of marriage, to have an abortion as a young married woman, to abandon the responsibilities of a good and faithful mother—and each time, she makes the “right” decision. The series does not deploy these themes didactically or even moralistically. Clearly Meyer was more concerned with questions of romance and supernatural beings than with instructing young readers how to lead their lives. What is interesting is how deeply fascinated young girls, some of them extremely bright and ambitious, are by the questions the book poses, and by the solutions their heroine chooses.
It appears that young women are tired of a culture where being a gentleman means not forcing yourself on the girl after she says no. There is something wrong with a relationship dynamic where it is the woman’s role to persist in holding off an infantilized male bent on going as far as she will allow, and ironically enough, we have left it up to a moody, vegetarian vampire to remind us of that fact.
