The main focus of the program though is positive. With the stellar reputation American Masters enjoys, they were able to interview nearly 50 people for the show. There are a great number of funny anecdotes, and vintage footage of first appearances from Seinfeld, Drew Carey, and others.
What I found especially illuminating is how Johnny Carson spent the years after his retirement. He was never in the news, and turned down all requests for appearances. Rather, he seemed to enjoy his retirement thoroughly, and spent a great deal of time reading in the yard of his Malibu home.
This American Masters biography of Johnny Carson is the best, and most informative one I have seen, and there have been a number of them over the years. This one is well worth tuning into, and does an outstanding job of presenting all sides of the television legend.
