True to lore???? Please, vampire lore at this point means do anything you want with them, including making them sparkle, or, as in a much loved children series, Bunnicula, making them a rabbit. The Twilight series is a romantic YA series about a teenage girl who is vaulted into adulthood by her love for a vampire and her friendship with a Native American werewolf. The main character is not Mormon, although the author is, and the Mormon religion does not come into the stories. And while, yes, her boyfriend has to turn down the impulse to eat her, she pretty much stalks him, and nobody rapes anyone. Other than presenting vampirism as a form of prettifying psychosis, Meyer commits no crimes, and it's hardly the first time that vampirism has been presented as prettifying psychosis. In fact, that's something of a tradition. That she went all Romeo and Juliet is hardly the first time someone wanted to try it, but her readers like her characters.
If you want prettified psychotic vampires in more adult-geared stories, there are plenty of them out there, and such series tend to move from vampires and weres into elves, zombies, witches, voodoo priestesses, fairy sprites, dragons, etc. Some are bestsellers -- Charlaine Harris, Laurell K. Hamilton, Kelley Armstrong, Kim Harrison, Patricia Briggs, Jim Butcher, Tim Pratt and Charlie Houston, because large groups of readers like their characters. There are also older series or books like Anne Rice's. Guillermo Del Toro took time out from his film schedule to hire Chuck Hogan to help him write The Strain, which no doubt will be a vampire film, game, breakfast cereal sometime soon. If you are interested in other YA series, there are quite a few that have vampires, weres, zombies, etc., ranging, as the adult fare does, from comic to horror.
Vampirism is open season. The only one who used the "lore" was Bram Stoker's Dracula, and even he threw out what mythology he didn't want and came up with Renfield. So just relax. It's not like they're real and going to file a complaint.
