Nothing wrong with any of those answers. It’s a tough question and one that can easily be interpreted differently by everyone. I guess if I had to answer in a hurry, I’d say GUNSMOKE. The western is the only film genre that is uniquely American, and GUNSMOKE is the most successful western series of all time. Not only was it enormously popular on CBS, it is one of the few shows that debuted in the 1950s that is still running today, somewhere, on some cable network or independent station.
