In fact, this show was about people reaching middle age, and the realization that they are no longer kids, and that their dreams might not get fulfilled. Of course, the fact that the series didn't last long is more an example of what the series was about: People maturing. In the youth obsessed media, people are becoming "undesirable" earlier and earlier. Where our role-models were in their thirties and forties, now when we hit middle age, all of the "stars" are youthful twenty year olds. We are has-beens before we were ever-was. That is what this show was about. And, it was slyly humorous about the situation.
One of the memorable writing involved the episode "Pig in a Python." Two of the characters are discussing how the baby-boomer generation changed American society. You could witness it like seeing a snake eat a mouse. You no longer saw the mouse, but you could see the effect moving down the body of the snake. "But, with us, it is more like a pig in a python." I hope that someday this reaches DVD.
