So I know many will snarl viciously at this, but...well here goes:
I've never had that much of a problem with the Twilight vampire lore. Yes, of course they are emotional and much more human than monsterish, and they may lack some of the traditional powers. But Stephanie Meyer wanted to put a new twist on vampire traits, and she certainly did. Now there are knockoffs, and influenced variations, AND plenty of the "old-school" vampires around. The great and awesome thing about vampire mythology, monster mythology, heck, mythological creatures as a whole is that it's MALLEABLE. It's anything you want it to be! Over the ages, and through different cultural periods, myths and fairy tales and their characters undergo fascinating changes, often reflecting the times. But even when a change becomes prevalent, that by no means dictates all following material. You'll find dozens and dozens of different versions of mythological phenomena, each one the product of a purposeful author, however stunningly creative or unoriginal that person may be.
So. I don't see the need to panic just because the "traditional" (whatever that means) vampire lore is manifested in a new and unique way--that you happen to hate. Don't like sparkly skin? Dive into gritty Daybreakers. Don't like the mushy romance? Read The Strain. Or go classic and get Stoker's Dracula. Can't seem to find anything? Well then, go out there and CREATE the next vampire epic! Shape your bloodsuckers into anything you want. You can bet countless others before you have.
*ahem* Sooo. Personally I enjoy child vampires. So creepy...and innocent-looking... I've always been fond of going against the current a bit, tho, so if I was to have my own...they would be either 1) surprisingly genial and funny and very down-to-earth about the fact that they have to drink blood. almost like they were on a special diet or something. OR 2) an extremely unsupernatural vampire...really, only vampiric thing about them is that they need to drink blood to survive and they act somewhat feral. ordinary clothes, no fangs, no fancy powers....just as if a human suddenly was gripped by this unstoppable thirst. having no instruments, they must drain their victims with...anything sharp, really, before lapping the krovvy up like a dog.
