Vampires are always with us. Just look at the paperback racks. Vampire romance novels and chick lit (sometimes known as "bite lit") are one of the hottest categories in publishing. And it seems like there's always at least one or two vampire tv shows on the air. Besides "Moonlight," we also just had "Blood Ties" on Lifetime.
I'm more impressed that we seem to have a mini-werewolf boom in the works. Besides "Underworld: Rise of the Lycans," we also have the upcoming remake of "The Wolf Man" plus some upcoming film about Mexican werewolves south of the border.
