I cannot call the series "Bob" one of the greatest ever, only because the fools at CBS didn't realize what a gem they had, changing almost everything after the first season, then cancelling it halfway through the second season.
For the first year, Bob was hilarious, with the same formula practiced on "The Bob Newhart Show" and on "Newhart", and, in my opinion, better success than on "Newhart." The actress (Cynthia Stephenson) who played his daughter added a delightful presence to the series. I'll never forget her line after her mother had committed a major blunder destroying a valuable item of Bob's. Speaking to the family cat, she lamented, "It's too bad that Mom can't live with us anymore." I consider "Newhart" to have been a fine show, and "Bob Newhart" one of the ten greatest comedies of all time. "Bob" had a first season that would have let it join those ranks, had it only lasted long enough.
