Had she tried to re-invent them & made them more AWESOME than say, The Lost Boys, it would have been fine. She took a myth based around repressed sexuality & made it both Lame & creepy at the same time.
The reason people, me included (& vampires have never been my favourite of all the "monsters" I'm a zombie girl at heart), have got all riled up is because there IS value in the creatures she's messing with.
Look at what the Blade character did with the Vampire myth, messed up all kinds of things, but it still had a backbone, spine and MADE SENSE.
The fact that the original Vampire myths came from many different sources & were then mostly characterised in the Bram Stoker novel, then we have had many layers of meaning from many different 20th century sources building it up to became something we all reckognise, even if each one is slightly different. Eg: In Lost boys he says "Garlic doesn't work"
Whether it's comic books like 30 days of Night, TV like Buffy, Novels like Anne Rice there is a sense of continuity in the use of Vampires, whats the point in calling it a Vampire if it isn't, she should of just called them Stalking Sparkle monsters.
Sorry if this is insanely rambling, this is because, I am & do & because I'm hungry, very hungry. Soz.
