Have Spinoffs Jumped The Shark?

TV spinoffs are getting more and more common, but are we ready for a spinoff of a spinoff? CBS’s “Young Sheldon” is already a spinoff of “The Big Bang Theory”, and it looks like IT’S getting a spinoff of its own. There isn’t a title yet, but I’m thinking “Slightly Older But Not Quite As Old As He Was on the Big Bang Theory Sheldon”. There’s already another “Big Bang Theory” spinoff in the works, with a mostly new cast, but guest appearances from the stars of the original series are possible.
