Actually, it's the other way around. Vampires used to be creepy, foul, evil creatures from the grave who took the blood from the living, eventually causing them to fall ill and die, losing their immortal souls in the process. Dracula, as he was created by Bram Stoker, had hairy palms and a rancid breath that caused shudders when a person got near him. He brought home infants for his vampiresses to feed on. Bela Lugosi, tall, dark-haired, elegantly-caped, and aristocratically-accented, softened that image somewhat in the 1930s when he starred as Dracula on the stage and in the movie.
It was in the 1970s, however, that everything really changed. Several Dracula movies came out in which the actor, e.g., Louis Jourdan and Frank Langella, portrayed the character as the total hunk, romantic, debonair, seductive. At the same time, Anne Rice's characters, e.g., Lestat de Lioncourt, Louis de Pointe du Lac, and Armand, also appeared and helped to change the vampire from creepy to cultured, from foul to fancy, from evil to elegant, from the grave to the goth. Instead of hunting the night for the hapless meal, vampires now took jobs as actors, detectives, and business moguls. Instead of dark castles, they lived in penthouses. Instead of feasting on human babies, they now got their blood from abattoirs (slaughterhouses), morgues, and willing donors. This vision of the vampire is the one that has predominated in the movies for the past 30 years.
With 30 Days of Night, we've seen a return to the pre-Ricean vampire, the creepy, evil killer that you don't want to meet on a cold, snowy night in Barrow, Alaska as opposed to the suave, rich prettyboy languishing on the French Riviera in his sunglasses and 1500 SPF suntan lotion.
