Game of Thrones, in its eighth and final season, is as big as television gets these days. More than 17 million people watched the season's opening. Judging by the fan and critic reaction though, it seems that a substantial portion of those millions are loathing the season. Indeed, most of the reviews and fan discussions seem to be pondering where the acclaimed series went wrong, with many theories on exactly why it went downhill.

The show did indeed take a turn for the worse, but the reasons for that downturn goes way deeper than the usual suspects that have been identified (new and inferior writers, shortened season, too many plot holes). It's not that these are incorrect, but they're just superficial shifts. In fact, the souring of Game of Thrones exposes a fundamental shortcoming of our storytelling culture in general: we don't really know how to tell sociological stories.
