Too many “what got cancelled too soon” questions, what’s a show that went on too long?
Hard mode: no The Walking Dead
Most of the original voices have left. The remaining can’t voice characters outside their ethnicity.
What? The 6 of them are all still there. Hank Azaria gave up Apu/Lou/Carl and Harry Shearer gave up Dr. Hibbert, but the vast, vast majority of characters are still being voiced by the same actors.
I do think that the fact that The Simpsons has been on so long that they had to go ahead and do that is strong evidence that the show has run its course + ought to end, but the re-casting is a symptom, not a cause.
Also not to be morbid, but IMO they should really think about wrapping it up before the main cast starts to retire or pass away. The actor who voiced Mrs. Krabappel already died, and I mean… Harry Shearer is 80 this year, and the rest of the cast is getting up there too. I guess they could always recast or (God help us) try to use AI or something, but yeah, they should try to send it off with a little bit of dignity left I think.
