For some, vampires are still firmly in the 'evil, scary' column. However, in recent decades, vampires also run the gamut from evil to morally ambiguous all the way to fangless and vegetarian. I think part of their appeal lies in their versatility. Vampires can be the villain, the hero, and everything in between, all depending on the writer's whim. You'll also never hear me say that anyone is doing vampires 'wrong' because unless a real vampire stands up and sets the record straight, it's anyone's game as a far as defining them in fiction.
