Vampires are so old that they don't need to impress anyone anymore. They're comfortable in their own skin. It's this enigmatic strength that's very romantic and old-fashioned. I think it goes back to something of a Victorian attitude of finding a strong man who's going to look after his woman.
I think one of the things that language poets are very involved with is getting away from conventional ideas of beauty because those ideas contain a certain attitude toward women certain attitudes toward sex certain attitudes toward race etc.
