I don't think the young adult books are on because they were assigned books at school. Several of the ones I put are young adult or children's books and I wasn't assigned any of them at school. I wouldn't put Frankenstein or Dracula on my list, though I read and enjoyed both. You can't put on ALL the books you've enjoyed, it would take up too much space. As for them being superior to the films, aren't all books?
I once went through a phase of reading all the lovely old Gothic romances and "Mysteries of Udolpho" was brilliant.
