I always enjoyed Lovecraft's ghouls - living eaters of the dead. I like the way they are monstrous and unappealing, but potentially sympathetic, ensouled beings. I think they could make an interesting counterpoint to vampires, who are appealing but ultimately horrific and villainous, since they must consume the living to exist, while ghouls only have to eat the dead.
Heh. That would make a great supernatural "romance." Horrible unappealing ghoul struggling to save the human girl he's become infatuated with from the sexy vampire she's fallen in with.
Ok, that's enough meandering from me. Also, this was a great link and thanks for sharing.
