I haven't read the Twilight series. I only saw the first movie. Personally, vampires creep me out, so the Twilight series doesn't hold my interest. However, I like Edward Cullen's philosophy; I just wish he wasn't a vampire.
(btw, have you ever checked out pictures of Transylvania, which is famous for vampires? It's a gorgeous country! Why would such creepy creatures come from such a place?)
On the other hand, I have read, seen, and bought all of the Harry Potter series. Magic has always fascinated me.
