Many sitcoms start out with great promise, but over successive seasons settle and turn dimensionally less realistic. Take for example Tony Danza's spiral down in "Taxi" into the "dumb guy." In WKRP in Cincinnati, the complete opposite was true. Two dimensional stereotypes at the beginning (cowboy programmer, dim-witted receptionist, lazy mama's boy manager, city-wise black DJ, etc.) were allowed over the show's course to become psychologically real. The on-going harassment by married salesman Herb Tarlek towards Jennifer the receptionist was finally confronted, and in subsequent episodes he was never quite the pig towards her as before. Alcoholism and drug abuse were addressed, but never in the "hit you over the head" PC style of today. The show could be simultaneously hilarious and of dire seriousness. If you can, catch the episodes in rerun in order. The final season is amazing, especially when the previous years have set you up for it. Carol Bruce (Mama Carlson) episodes are especially stunning. And always look for Les Nessman's roaming band-aid.
