Attractive Vampires?

It is discussed in chapter two that a woman named Margaret Carter "suggests that while the nineteenth-century vampire might have inspired sympathy despite its curse, in the late twentieth-century it 'appears as an attractive figure precisely because he or she is a vampire'" What do you think changed dramatically over the generations to make vampires less scary, and more attractive and/or appealing? Why is it that shows such as True Blood or movies such as Twilight show vampires as an intriguing idea rather than something to run and hide from?
