I think TV came westerns across differently then the movies. Healing of the nation had happened by the time we were making movies and the hero protagonist could have been Billy or Johnny. On TV Westerns I can only think of Union folks. The big three ranch owner families, such as Bonanza, The Big Valley and The High Chaparral and in the other shows.
edit: I looked up The High Chaparral they had characters from both sides of the war
Anyone else looking forward to Longmire on A&E? It seems to be the modern western/cop show
