working9 - excellent point. I have indeed read War and Peace, Middlemarch and Joyce etc etc. But I also love Angel/Buffy and even at times, Home and Away. I can talk about the role of coincidence in Hardy and have a passing knowledge of Hansen in Holby City.
The cleverest mainstream writers really know their classics - because there will always be elements of that familiar literature deep within their work.
Example: the word 'dumbledore' is Victorian and is seen in Hardy's Mayor of Casterbridge. Hermione is a classical name. Rowling was a bookish child who absorbed everything and produced something old-fashioned, for a modern age.
But it is odd that millions of adults assess the books by adult standards. She is a children's writer and it is what it is.
So of course I am biased. She has put a lot of people in work, kept a roof over our heads and sparked so much creativity: set designers, prop makers etc.
There is undoubtedly a snobbery amongst literary folks but I am not one of them. Publishers are struggling - really struggling. Those Jordan biographies subsidise the literary books. Big names sell and keep our tender book industry going. I am a writer, my OH is in films.......long may imaginations be sparked.
