Sex appeal comes from physical appearance, demeanor, and mind. Just because you're horny all the time doesn't make you sexy.
Far be it that vampires possess a supernatural seductiveness. Sure, they have lust and go after virgins, but come on, they weren't appealing. Vampires were ruddy and bloated, due to feeding on human blood.

Every author has a different view on vampires. I personally like Laurell K Hamiltons take on vampires the best.
But not every view is accurate. It rapes the whole vampire folklore, which is disappointing.

What is so scary about sparkly vampires, anyway?
It's an inaccurate portrait of the vampires of folklore.

Nothing. There is no reason behind the sparkling; I am a bit of a scifi nerd, but living (and ex-living too) have reasons why they appear the way they do. Traditional vampires don't have pigmintation in their skin, so they burn in the sun. The same concept is present in I Am Legend.
Traditionally, vampires were not vulnerable to sunlight. The only vampire that I am aware of that fears sunlight are the vampires of China, the Chiang-Shih. The idea of vampires being vulnerable to sunlight came from the movie,
Nosferatu, which was directed by F. W. Murnau.

name a good vampire book then
Dracula by Bram Stoker? I've never read it, but it's a classic, and the idea of Dracula originates from that book.
