But then that knocks out shows like The Waltons and Little House on the Prairie, both of which were absolute fantasies. One of the few decently authentic treatments of rural life I can think of was in the movies, "Country", with Jessica Lange and Sam Shepherd. And it was so authentic (and heartbreakingly real) that the vast majority of people did not get it at all. I remember going to see that movie and hearing people talking about it as they left and thinking, "Wow, talk about a culture gap." It went beyond a class gap. But then, class plays out in an entirely different way in rural societies, in large part (IMHO) because farmers are the largest backbone of the society, and they have a mix of stereotypical characteristics of both lower- and upper-class (manage their own business, do manual labor, perform their own maintenance, write paychecks, etc).
Back to TV....The Office, maybe? Comedy, but pretty gritty at that. The Rockford Files was pretty downscale, and unapologetically so.
