Similar? Ah...no. Not even close. It's merely their mutual history of having a "cradle robbing, creature of the night boyfriend" that puts them anywhere near the same "vampire" region. Check out this article from Salon.com by Laura Miller. http://www.salon.com/books/review/2008/07/30/Twilight/
We will make this excerpt your quote of the day since work is keeping me too busy for frivolous quote research.
"Comparisons to another famous human girl with a vampire boyfriend are inevitable, but Bella Swan is no Buffy Summers. "Buffy the Vampire Slayer" was at heart one of those mythic hero's journeys so beloved by Joseph Campbell-quoting screenwriters, albeit transfigured into something sharp and funny by making the hero a contemporary teenage girl. Buffy wrestled with a series of romantic dilemmas -- in particular a penchant for hunky vampires -- but her story always belonged to her. Fulfilling her responsibilities as a slayer, loyalty to her friends and family, doing the right thing and cobbling together some semblance of a healthy life were all ultimately as important, if not more important, to her than getting the guy. If Harry Potter has a vampire-loving, adolescent female counterpart, it's Buffy Summers.
"By contrast, Bella, once smitten by Edward, lives only for him. When he leaves her (for her own good) at the beginning of "New Moon," she becomes so disconsolate that she resorts to risking her own life, seeking extreme situations that cause her to hallucinate his voice. This practice culminates in a quasi-suicidal high dive into the ocean, after which, on the brink of drowning, she savors visions of her undead boyfriend: "I thought briefly of the clichés, about how you're supposed to see your life flash before your eyes. I was so much luckier. Who wanted to see a rerun, anyway? I saw him, and I had no will to fight ... Why would I fight when I was so happy where I was?" After Edward returns, the only obstacle she can see to her eternal happiness as a member of the glamorous Cullen family is his stubborn refusal to turn her into a vampire: He's worried that she'll lose her soul."
Catching stuff, ain't it?! Yeah, you're hooked reader, just admit it. No one is going to judge you here, trust me. And for your patience, some pretty romantic pictures! See Bella and Buffy with their sultry, brooding vamp boytoys below.
