Query: Disappointing

I am in my late 20s so I was watching sesame street in the late 70s and early 80s.I expected a nostalgia trip and was satisifed in many respects.You wonder about Borgenicht's audience for the books as the book seems to be directed at adults, yet they have a lot about Elmo, Zoe, and things that happened on the show during the 90s. Those things I have no interest in and I would have rather they spend the extra pages on a more detailed history of Cookie Monster, Count, Ernie, etc.Overall the book seemed to try to be all things to all people and satisifed none completely.
