Columbo is as endearing today as he was 40years ago! The man in the rumpled raincoat never loses his charm. My adult children like him and my grandchildren as well. What is the secret of his durability? I'll leave speculationto others. As for me, the unique detective never bullies or tries to intimidate suspects. There are no car chases,no shoot outs, no graphic violence. Maybe THAT is the reason he is so loved!
