I would like to see a book that talks more about the characters and performers. This was one of my complaints, but I realize it would be hard to fit in. He talks about Grover and Bert and Ernie's beginnings very briefly, but the only characters that really get discussed at length are Big Bird, Elmo, Zoe and Cookie Monster (not quite as much as the other 3). There's also a bit on Abby. Now that I'm pretty much through with the book, I think that discussing character origin, development, and why some were ultimately taken out of the show (such as Don Music, Sherlock Hemlock and Lefty) should be in a seperate book. Hopefully a book like that will be released.
There was very little about Telly and nothing about Baby Bear. The same could be said about Marty Robinson and David Rudman. There was very little about Marty Robinson in the book, and (virtually) nothing about David Rudman. They're two performers who have been a huge part of Sesame Street through the 90s and this past decade. There were also a lot of other performers and writers that were overlooked (such as Joey Mazzarino, who is hillarious as Murray Monster, and is both a performer and writer).
Another thing I noticed was, although Jerry Juhl is quoted a couple of times, he received no credit for his involvement in Sesame Street. He wrote alot of Muppet stuff (like Ernie and Bert) during the early seasons.
Again, these are just some minor complaints. The book is fantastic! I love how it focuses on the people truly responsible for the show, people who rarely get the credit they deserve. And after reading it, it made me really appreciate the new format of the show more. It makes sense. But I also agree with Jon Stone in that the show should not have tried to be Barney. It was interesting noting how one reviewer compared the two, praising Barney for being "slow" and "familiar" and teaching the most basic things, and essentially bashing Sesame Street for being too deep. Competing with other children's shows doesn't mean lowering yourself to the other show's level. Kids deserve better than Barney, and Sesame Street, for all the problems older fans may have with it at times, is still the best.
