Vampires or werewolves?

Gotta be vampires really. There's something very y about neck-kissing generally, so there's that aspect. Underworld is a great film for the y vamp thing too. But it's also the undeadness of it all. You're like that all the time and don't have to go through the whole "change" thing, unless you choose to be a bat (depending on which legends you subscribe to). And wolves are pretty stupid compared to humans...
