There seems to be a big market in Vampire stories at the moment and this, of course, has happened before. It will pass go full circle and come back again. These supernatural beings are becoming more like anti-heroes in some sagas as opposed to the demonic blood sucking beings that usually have been. They are cropping up in teenage stories, being good guys that still need to drink blood but take it in other ways. There have been police detective TV series where vampires help solve crimes, fall in love with humans - the list goes on. I think the public will never tire of vampires - good or bad - you decide.
