This question came up earlier today, and I am curious to see the variety of responses here on Tildes. What is the oldest TV show that you actually enjoy watching? Not just enjoy it "for its time", or respect for its influence, etc, but really enjoy in the same way that you do modern content? I am curious where the cutoff is for most people.

For me it is probably The Twilight Zone, which 1959 and which I just absolutely ate up. But after that there is probably a few decade gap to maybe the 1970s with Rockford Files or maybe 1980s with a couple of shows, including TNG.
