Okay... I take it now that you all think Sesame Street is actually ment for nostalgic 20 year olds, and not kids....
Seriously. I would NOT like to see them go out, for 2 simple reasons...
A) It's still the best educational show on Television. It seems to always will be.... look at the other crap on the channel. Boobah. Teletubbies... Jay Jay the Airplane.
B) Do you really think it would be replaced by a show just as good in quality? Shell no! It could easily be replaced with some forgettable poorly made crap used to sell toys to 3-5 year olds like 90% of the other shows on PBS. I mean, seriously. Over here it took Mister Roger's death to have them air Mr. Roger's Neighboorhood again, and not the flimsy little puppet show or whatever that was on in it's stead.
After all, Kids are the main target for SS. Do you think they care to see a nostalgic clip from 1970? No. They would rather watch Elmo. They're losing a lot of competition from quantity garbage on most of the other networks. Kids sympathise with Elmo. Do you think they feel the same as Forgetful Jones or Don Music? Not totally. Pretend that your a little kid, what character would you mpost likely pay attention to, a character that resembles the psycological age of a 3 year old, or something that's a parody of something that you've never heard of? The reason why Guy Smiley and the rest aren't on the show, isn't because they want to deny the nostalgic fans, but because kids get fidgety when they're on. They feel they can play with Elmo. He could easily come out of the TV and be your friend.
Now look at it this way. Your 20 years old, and it's 1975. What do you think whne you watch the show? "You gotta be kidding me!" or if you're watching Pinball number count or Jazzy spies you think... "Pfft! What the shell are they on?"
I mean, as much as I'd like to see the show become more nostalgic, you have to think realistically. It's a show for kids and parents to watch together.
But besides that, I do agree that they overperfect the characters too much (I feel the same way about Gonzo and Fozzie). Bert and Ernie reached peak great looking ness just before Jim Died. I'm still unsettled about Cookie Monster, and the new Grover looks too dead. Plus I do agree that they could have easily shaved a few bits donwn for more classic stuff.
