This article is just for the fun of it. The theory is that the HBO show “Game of Thrones” changed substantially in tone and feel during its latter seasons because fewer words were included in each episode.
I always think of “Freakonomics” by Stephen J. Dubner and Steven Levitt when anyone sagely suggests that fact A must be the cause of consequence B, when they may have nothing to do with each other. For one thing, as noted below, the increasing number of battle scenes changed the tenor of the show in many ways and reduced the number of words spoken in each episode. For another, the show went beyond what George R.R. Martin (the author of the books underlying the show) has yet published and thus the show’s writers lacked the guidance of the tight construction of the books. Many reasons, but people will argue endlessly anyway.
