Before you flame, hear me out. Yes, I think Twilight is a blight on the world that should of come to be. However, I been thinking that the sparkle vampires is just the grim result of the mythos of vampires. Look back at what vampires was like.
Nosferatu, 1922.
Vampires were monsters, pale, weird, dangerous, and scary. That thing doesn't even begin to look human. This is what was in mind when Dracula was written, this is what vampires looked like until...
Still scary, but more dashing I guess, could pass for a human. For the most part vampires stayed like this. However, the mythos was slowly dropped from here. Some tales said that cow blood is just as good as human blood. Vampires stopped being pale, stopped wearing capes. The wolf transformations just are forgotten, bat transformations have been more or less phased out. Teeth became retractable so humans don't notice. The ugly vampires at times appear, like in Buffy or in Blade, but more often they are either really powerful/old vamps or could make themselves look like regular humans. Some times the death by sun either required some decent amount of exposure, could be circumvented with technology or simple became an irritation.
Keep going on this trend of more human vampires with the mythos steadily dieing... does the sparkle vampire seam like it is to far out of reach? It is sad that we reached this point, and vampires show signs of going back to the old days with "Daybreakers," but there denying that the huge pile of money that anything Twilight related brings means that... sadly, Sparkle vampires are here to stay.
