Yes, just like everyone else here, I LOVE the Muppets.
And yet, there are some things about them that get on my nerves from time to time. I never had a liking for Miss Piggy. Don't get me wrong, but I couldnt really stand her voice(especially when she sings-like in TMM). Same with Marvin Suggs...why couldn't he talk more like Cookie Monster? that woould have suit him better.
Even with Sesame Street, there are things that bug me. I don't either love or hate Elmo(I didn't really know him that well when I first started watching SS), but I hate that Elmo's World has eaten up the last half of the entire show. For some strange reason I was never really into the cartoons or live-action films. Don't know why, just interested in the Muppets.
I've watched most of it from the early 90s and some from late 80s(memory's still fuzzy about them, but I know I've seen them as I was born around that time), but when looking at the Episode Guide for the 70s episodes at Muppet Wiki, accompanied by some clips from those days(including some from those episodes)...I thought: Wow, THIS was the real Sesame Street! It felt like seeing a real street populated with real kids and adults playing and having fun together, and Muppets up to their little shenanigans. And none of this "cutesy-cutesy" stuff that would eventually happen years later. The early 90s(1990-92 era: Ok as well I guess, but hey, I think the 70s was the real deal).
The things on SS I can't stand are: the "Around the Corner" era(especially the 29th season), Baby Bear, Natasha, Monster Clubhouse, any of the "nursery Rhyme" and "fairytale/magic" nonsense(in Newsflash ok, but ON the street NO!), Hero Guy, Elmo's World(except for maybe a few cameos from some classic characters)...Zoe and Rosita: I don't know...
