I agree, except the stuff they made in the Jim era was because Jim was around. It seems to me that even though there have been some quality productions since his passing (Treasure Island, Christmas Carol) that pretty much everything has been something of a dissapointment.
The Muppets don't seem to have the same magic without Jim. In this post Jim-era world, I think we pretty much have to settle for what we get. If that means we get a mediocre Fairy Tales spoof production that has only *some* good qualities, but is otherwise a stinker; or a cute story about Kermit's youth that has the potential to get younger kids into the Muppets, then so be it.
Kids got into The Muppet Show in the 70's and 80's because it was fantastic. Because it was Jim's. Remember how Eisner became dis-interested in the Henson property once it meant that it didn't include Jim's mind? Not very many kids became Muppet fans as a result of Muppets Tonight. To be fair, it didn't stay on the air very long, but it also wasn't anywhere near as outstanding as TMS. To be honest, I think all of the current Muppet writers need to move on to other areas.
The only way we're ever going to get anything like we had before 1990 would be if Jim came back. But that's never going to happen so we have to settle with what we've got. I'm sure there are plenty of creative minds out there who could breathe new life into the Muppets again -- writers, creative consultants, directors -- but so long as they keep churning out lesser than great stuff that doesn't make money, other studios aren't going to want to distribute it and thus no new minds can come in and save the day. That's why it feels like every Muppet production these days is a struggle.
Maybe that's just me.
In any case, as careful as I am with jumping onto the excited bandwagon for KSY for fear of being let down, I'm looking forward to it being, at best, a darn cute production that *most importantly* SELLS WELL.
