George R.R. Martin! The first books of the Ice and Fire saga were quite interesting, but he was SOOOOO long bringing the next books in the series that I lost all interest in his "work". I for one, will no longer support an author who has so little regard for the fans of his work. "A Feast for Crows" was junk, and wasn't even readable.
There are too many good authors out there, IE David Weber, John Ringo and others, that produce satisfying series of books, to waste time and energy on Martin's musings
