Stephenie Meyer is the woman without whom none of the Twilight world would exist. So you can either celebrate or blame her for that.

She was very specific about what she wanted from any adaptation of her work for the screen.

“The vampires have to have the same basic rules as the vampire world I’ve created, which means no fangs, no costumes, they have to sparkle in the sunlight, the characters have to exist by their present names and you can’t kill anyone that doesn’t die in the book.”

“It was a horrifying experience, I had realized that it could go wrong, and that it could be done badly, that they would do something that had nothing to do with the [original] story, that was shocking to me.”
