Vampires - the bad or the good

Have you ever wondered how did it happen that vampires, the bad guys in many scary stories, they suddenly became the good guys?

In Bram Stoker's "Dracula" (1897) vampires are cruel and terrifying yet in the modern culture they're often the good guys.. like David Boreanaz in Buffy.. Was it right what Edward was saying? Vampires are perfect predators - they're pretty and fascinating, they draw us closer in order to attack when it is least expected…

So are they good or bad? What would you prefer them to be? Or shouldn't we assume at all that the world is black or white? Let's hope for grey and other colours..
