This isn't ending the show guys. There are probably thousands of people out there who can pull off a perfect Flanders, Burns or Smithers voices. All FOX needs to do is pay them like 1000 dollars an episode. This will save them millions of dollars too.
when it comes to voice acting, you can never perfectly match. sure, there are a hundred videos of people doing flanders, but harry shearer didn't have to do a flanders impression - he was flanders. it always sounds off, and when it comes to that many characters... woosh!
of course simpsons is still gonna run cus it's a golden goose, but i feel like this might drive a lot of people away
