Seriously - I see no reason why a writer can't at least make some attempt to appeal to the 25,000+ die hard fans of a book as well as the 25,000 or so new fans. There is no reason to alienate one in order to appease the other, imo. No, you can't make all the people happy all of the time, but I feel that a writer should make *some* attempt to please those who have enjoyed a book prior to his/her coming on board.
It's why I'm having such a hard time with Azzarello and Chiang. Love the art. Love the overall story. Don't like the changes to Diana's world, supporting cast and history and I fully understand why some older fans have abandoned the book altogether.
