Game of Thrones began as a cultural behemoth and then ended as a cautionary tale as what could happen when a show goes on for too long. By Season 8, the source material had long been overlapped and the action had become so bloated that wrapping up every storyline was going to feel rushed no matter what. Now, as the Game of Thrones universe begins to grow, there seems to be an air of caution: spinoffs are being delayed, canceled, or moved to animation.
