I'm not big on vampires either. Many folks on my friends list (Livejournal) are freaks for Twilight, but I'm not one of them. It's okay writing, but it's really a teen book.
It's as if Stefanie Meyer had this huge burden to be in a vampire story, so she self-inserted her teen self into her pages.
Funny enough, I heard the movie actually *improves* the book.
I refuse to see the movie or read the books on principle, though. Friends of mine were treated unfairly due to a free ticket fiasco at a comic shop (long story - they were the ones giving away free tickets and the shop didn't receive them)...and also due to the whole teen mob mentality (San Francisco teen mob scene plus Robert Patterson plus too many people = not good.
