I love how 'real' Stephenie's vampires seem. It makes much more sense that they can't come out during the day because they sparkle, not because they would turn to dust. At least to me it does.
*Okay, don't kill me here, because I've seem the error of my ways* but, originally I didn't get into Twilight because I am a HUGE Buffy fan and LOVE Joss' vampires (love Spike!!!). I even had the flair on my facebook that said Spike could totally kick Edwards a**. <pause for the GASPS of horror>. I thought that Twilight was completely crazy because I saw a preview for the movie and Edward was out during the day. I would joke about it with my sister who was in love with Edward (BTW, she's the one who finally got me to cave and read the books, thank all that is holy that she didn't give up!) Since then I've done a complete 180. I am intrigued by how their skin is marble-like, how Stephenie describes their beauty and why they are beautiful, the way their eyes change when they're hungry, I could go on and on. I think about the Buffy vampires now and they seem rather simple to me, like too cliche. I'll take Edward over Angel any day.
p.s. I have since replaced the flair that won't be named with like a million pieces of flair about Twilight
