I think it's cyclical. Zombies have been around for ages, and vampires have run their course; we've had so many vampire movies.
One of my favorite vampire movies is 'Nosferatu,' which has a palpable sense of dread that's a pre-war dread.
'Interview with a Vampire' is my all-time favorite. I also loved 'An American Werewolf in London.'
I was under the impression that if you've read one vampire series for young adults, you've read them all.
