THE FUSE

Most spinoffs expand their flagship shows in a direction. That direction could be forward, following a beloved character past the events of the original story, á la “Frasier”; it could be backward, fleshing out the origins of a person or place with pre-established significance, the approach taken by both current “Game of Thrones” offshoots. It could even be lateral, simply transferring a concept to a different setting within the same universe in the time-honored tradition of procedurals like “CSI” or “Law & Order.”
