Put another way, Bella (Kristen Stewart) does not say no. More like "whoa" when she firsts spots the entrancing Edward Cullen (Robert Pattinson) in the high school cafeteria.
Edward is the most striking member of the Cullen clan, a very pale, very standoffish group of students at the Pacific Northwest high school where bounced-around Bella has just enrolled. She's naturally intrigued and secretly thrilled when paired with Edward in biology lab, but her presence seems to unravel him and he withdraws and acts like a jerk.
It's straight from the Tiger Beat letters page: He's so handsome, so obviously into me, but so rude!
Edward hints at a dark secret, and Bella notes that the local Indians give him funny looks. She consults tomes of aboriginal legends to ferret out the awful truth, and Edward explains the relationship implications: He's a vampire, and his longing to be with her is inseparable from his longing to sink his teeth into her.
Dracula might have put it this way: I vant to suck your blood.
The movie, and the "Twilight" books, overtly conflate this urge with sexual desire, as vampire stories always have. The genius of the Twilight series is that it merges the mysterious sexuality of the vampire with teen girls' interest/anxiety about sex.
On that score, Edward has archetypal appeal. He is powerful, handsome and completely devoted, but functions as chaste protector - romance without the icky mess.
Older viewers are likely to find this comical, as when mind-reading Edward rescues Bella from a drunken band of sexual harassers, and spares her their "vile" and "disgusting" thoughts.
Really?
Vile and disgusting?
Can you give me an example?
But there is nothing to sully the purity of the Bella-Edward bond, and he finds other means to prove his epic love - first saving Bella from an out-of-control car, then interceding when an out-of-control vampire gets a whiff of Bella's irresistible blood fragrance and stalks her.
