For the same reason people like "Abducted by the Highlander" (include glossy naked-chest dude cover) and "Taken by the Billionaire" (include suave dude in a suit on the cover) garbage?
I tend to like vamps if they work as a good mix of sex, violence, and power, and the author plays around with it. They need to be different enough from humans so there's a point to them not being human, but if they are just a scary monster they are boring too, as that could be anything else as well (a shark, for example ^^). Something that struggles between those two options works best for me.
Obviously that's basically never a theme in vamp romances ^^
