Guess I am not all that big into vampiric fiction, so I haven't run across any of what you are talking about. Other than anthropological works containing deep studies into vampirism and its origins, the last time I read or watched anything having to do with vampires was back in high school when the first seasons of Buffy the Vampire Slayer and all of its Sarah Michelle Gellar goodness where airing on TV; and most vampire lore strictlers tend to shun that show. I guess those vimpire romance/porn novels (Twilight and its hoards of clones) are a pretty big thing these days, but I personally think all that is a sad waste of the vampire mythos (not to say that Buffy wasn't).
