I'd have to say, I'd've liked MCC much more if they cast Sam the Eagle as Scrooge... yes just that.
I think if The Muppets is a sucess we'd be seeing a complete ressurection of the Muppet franchise. TV show is a maybe, seeing as when Disney bought the franchise they didn't have the TV show that'd be risky ground...
To me, a perfect MCC would have had J.P. Grosse as Scrooge, Scooter as his overly cheerful nephew... and it would have been a late 70's/early 80's TV special. But that's just me.... Seems if Richard didn't die before they made MCC, Scooter could have been the nephew. heck, ANY Muppet should have been the nephew.
They were trying to reestablish the brand, but did so with the main cast playing other characters rather than being themselves. The film that followed it was MTI and they were doing the same thing. Sure, Gonzo is always Gonzo and Kermit is always really Kermit underneath it all, but this just created a needless veneer compounded with a new Kermit voice and performance and the noticeable absence of Jim's specific spark for audiences to accept. And then Muppets Tonight finally rolled around and they stuck Kermit in the background. The same goes for MFS. The only time Kermit was heavily featured was in studio recorded albums. Considering that people are most sensitive to sound, Henson Co should have established the new Kermit character in film and television before cutting an album. This was never quite achieved.
MT was proof they weren't extremely confident in Kermit at the time. He kept getting tertiary roles in his own movies. MFS was a slight improvement in terms of Kermit's role... it took them until VMX, 10 years after MCC to really bring the frog back out. And say what you will about KSY... VMX and KSY WERE all about the frog. I don't know if it was a decision by Henson, or Steve just wasn't all that comfortable with him yet, but it was clearly something they had to work around with.
I will say, MCC and MTI were at least well written and some of the songs were glorious (though Jim Hawkin's high alto kinda ruined some of them), where as MupOz was just... it was a jumble. Bad casting, bad concepts, just... bad all over. Yet, it was the first time the Electric Mayhem performed vocally in a while. But with all the other, superior sounding scripts that were thrown around after VMX, it was a shock they went with something so... so gimmicky. Even if they had to do a WOZ storyline, they could have done it MUCH better than a clear and obvious tie in to American Idol (which explains the FOX involvement), and "borrow" from other versions of the story.
