A spin-off is a TV show derived from already existing work, often created from a supporting character of the original program. In this sense, the first spin-off in history is maybe Homer’s Odyssey, that follows the Iliad, and the last one is House of the Dragons, Game of Thrones’ prequel. Can one do something new with something old? Is the spin-off a desperate way to give artificial respiration to a show? A false good idea? Or a real source of inspiration?
