I do wish Steve and Matt well. I really do.
That said, I've having trouble caring about the direction Disney will be taking this franchise in the future. I haven't been too keen on really anything they've done in the past few years and it's become very clear now that what they want for the characters is something very different than what Steve thought was best, or what Jim would have wanted. The more the original core Muppeteers have passed on, retired or, in this case, have been fired, the more the soul of the Muppets has faded. I'm kind of at the point where I don't really care what their future is, because the IP sucking black hole that is the Disney Company (IMHO) hasn't done right by them in the past decade or so. One feature that was financially and critically successful, sure. But another that bombed and a TV show that had to be retooled thanks to low ratings and ended up cancelled anyway.
And of course, the Muppet presence in the theme parks has been de-themed to the extent that the closure and replacement of both Muppetvision and Pizza-Rizzo could be done in a weekend. In fact, I wouldn't be shocked if this is why Muppetvision is in the state it's in (the fountain becoming a planter, simplistic signage, the removal of the balloon) so that the turnaround time to make it something else entirely would be fast and cheap.
To Disney, the Muppets are nothing compared to Mickey and Friends, the Princesses, Marvel, Pixar and Star Wars. Do you really think they care if people are upset that they canned Whitmere and plan to go in a new direction.
Dark times are a-comin' kids.
