The Washington Post has an article on Harry Potter commentary:
As author J.K. Rowling has built her fantasy world to the extent of thousands of pages, and disseminated it in hundreds of millions of books, she has become the preeminent storyteller to children of our time. Her ideas and values, such as they are, have unprecedented influence. If there is such a thing as Potterist worldview, it must be ferreted out and scrutinized.
