Or just spinoffs in general.
This one was particularly offensive, though, given how actually good the original show was. Yes, even worse than Joey.
"MASH" was one of television's most popular and successful shows spanning eleven seasons. Its final episode is still the most watched episode of television in history, attracting an astronomical 125 million viewers ("Seinfeld" only attracted 76 million viewers). Spinoff? OF COURSE!
Naturally, CBS decided that, given the show's popularity, a spin-off show would be just as popular. Don't remember "After MASH" and the wacky adventures of Colonel Potter, Klinger and Father Mulcahy? Don't worry, neither does anyone else, because it was quietly swept under the rug after two seasons.
