Overall the short four-year run of this series was enjoyable. This is due in large part to an excellent cast, including (of course) Bill Cosby, Phylicia Rashad, and the late Madeline Kahn. The supporting cast, including Doug E. Doug and T'Keyah Crystal Keymah, was also wonderful. The show was clean, hip, and classic Cosby. Some classic moments in the beginning; after Madeline Kahn left the series (and sadly passed away shortly afterward), it was never the same. Darien Sills-Evans is a good enough actor, but he was no substitute for "Pauline." In addition, COSBY unfortunately became CBS's dumping ground for government-sponsored "public service messages" disguised as sitcom plots. In COSBY's last days, the scripts weren't as good anymore either; uneven writing in the end was what did the show in, leaving behind some classic moments from the first few years.
