Schitt's Creek gave each of its central characters a happy ending with a bright future, which perfectly sets the series up for a well-timed revival. This would, of course, require caution and care so as not to diminish the satisfying close of the original series. The popularity of reboots and spin-offs in recent years has proven that there are right and wrong ways to return to a story, especially one with such an emotionally impactful end. It would have to be timed right and set up in a way that doesn't contradict the trajectory of each character's happy ending.
