Because for all their Meyer-flavoured trappings, that's what Edward and co truly are. They're vampires.

Yes, they sparkle in the sun. Yes, they don't have fangs. But Cullens aside - and this wasn't always the case - they're only too ready to tear the flesh from your body and snack on you like a Happy Meal.

What's less shocking is the fact that Twilight's creator really isn't a big fan of the traditional fang club.

"I am not a vampire fan and I never have been. I don't do horror. I'm an enormous scaredy cat.

"Hitchcock is about as much as I can handle and I love it, but anything more than that and you're not going to see me in the theater. And I have never gotten it – why are people obsessed with vampires, you know, and I know a lot of people who are.

"I'm actually surprised now I know how many more people are, and so the fact I would write about them is wildly out of character for me and bizarre, and nobody who knows me believed it for a really long time."
