There are some TV shows that you don't want to end, but when they do, they don't end the way you wanted.
Bad Robot / ABC
Were you annoyed at how Lost ended? Did the finale of the original Will & Grace (Will and Grace both had children who then became friends) frustrate you?
NBC / Universal
In the revival of the show, Will & Grace pretended that it never happened.
What about the ending of Roseanne? Seinfeld? When Liam didn't win Bake Off? It can be from any show, even shows that are popular, or fiction or reality TV.
