#18: Mrs. Columbo
With 13 episodes spread across two seasons, Mrs. Columbo was a crime drama following in the footsteps of Columbo (1968-71). In it, Kate Mulgrew starred as the wife of Columbo, who works as a crime-solving reporter. During the run from 1979-1980, they tried renaming the show to both Kate the Detective and Kate Loves a Mystery to get audiences to like it. But nothing could save this enterprise. Ratings never improved, and the series was canceled.
