Some TV shows become so iconic that they inspire spin-offs, but not every one is a hit. In fact, some spin-offs flop so badly that they almost tarnish the legacy of the original. Here’s a look at the most infamous spin-offs of all time—shows that fell short of expectations, failed to capture audiences, or simply missed the magic that made their predecessors great.

The Tortellis

In the opening scene of this *Cheers* spin-off pilot, Nick Tortelli faces a nightmare where he’s condemned to hell for cheating on his wife, Loretta. But things only go downhill from there. Nick’s complete lack of redeeming qualities makes it difficult to root for him, either in love or business. Meanwhile, Loretta is depicted as so exaggeratedly clueless that she feels more like a caricature than a real person. Fans found the Tortellis too over-the-top to tolerate, and without the charm of the *Cheers* bar, this family struggled to win any affection.
