Advertisements On the whole, they've been "adjusting" the books to fit the TV show more and more past the first season. Cutting stuff out, moving stuff around, consolidating things. It's both necessary given the vast amount of material to be covered in a limited TV season, and good considering how...shapeless the books increasingly become. Books 4 & 5 in particular are a structural mess, because of Martin's meandering and because of the way they were written and published (conceived as a single book that meandered out of control, and divided in a way that, in retrospect, probably didn't help). I still enjoy the books, but I suspect as the series progresses the show will in some ways become an improvement over the books, especially in terms of structure and focus.
