The most legit recent vampire movie I have seen is Daybreakers, it has a pretty original approach to vampires, also you should check out the movie Thirst (USA) also known as Bakjwi which is a really good flick, I think its out of South Korea and directed by Chan-wook Park.
And I agree glittering diamond encrusted vampires don't deserve to be called vampires, how bout sparkly-huggables as a name instead....
No Sig For Now....
