Of any of the scary-monster genres, vampire flicks have got to be the most tired at this point -- even zombie flicks are generally self-aware enough to put some kind of new spin on things anymore. Maybe vampires are just naturally marketable enough to be boring.
Whatever the case, they're pretty much soap opera characters that only go out at night, are immortal and feed on the blood of humans -- none of which are very far off from your general soap opera conceits anyway -- they're petty, promiscuous and attractive, and they've got a penchant for betrayal. Voilà: The Young and the Restless who are also Vampires: Black Fingernail Polish Edition. And can we make sure all the dialog is rendered strictly in monotone? Because vampires are not only boring, they are also very bored.
