MY opinion:
Vampires have always represented evil.Hollywood is subliminally trying to excuse evil(unless it’s a Christian) by explaining their behavior in humanistic terms while portraying the vampire(evil) as victim of circumstance.
So, if virtuous people get turned into vampires against their will, they have to be evil?
Vampires have been moving away from being always evil for a long long time. Starting with the comedy Love at First Bite, continuing on through the excellent TV show Forever Knight, and then beginning the turn towards romantic figures with Ann Rice’s Lestat series, and now a mormon in Scottsdale has turned them Emo.
