I don't know if watching the movie screwed my appreciation of the book. I do love the extra details that the book has and that I can now identify in the movie after the fact. There were scenes that I liked better in the book. It's not erotic in the sense of smut, but romantic over dirty. There's very little explicit content. This is a romance book that actually makes you think and there's more than just the sex. I read that this story started out as Twilight fanfiction. I'm not sure that's completely accurate, but I can definitely see some parallels.
