Columbo is infinitely rewatchable -- well the ones made for the 1970s NBC Mystery Movie wheel. I am less fond of the 1980-1990s ABC version. The original pilot Prescription Murder (1968) shows a youthful Peter Falk as a much harder edged Columbo than appeared in the regular series matching wits against Gene Barry. It took like two or three years for Columbo to be a regular series after the pilot. That would never happen in television today. I haven't seen it in syndication for a couple of years, but I am sure it will be back sometime-- maybe on your beloved Antenna TV Fatty -- as it is a perennially syndicated show like Hogan's Heroes or The Brady Bunch
