Downton Abbey. Six seasons (about 10 episodes per season). Hour long drama--no commercials if you watch PBS. So its a bit of a commitment. It follows a family of nobles from 1910's through the next decade or two. The world is changing and the nobles are trying to find their place in it. The stuff you see on the screen is about 1/2 of what goes on upstairs and 1/2 what goes on downstairs. The servants are featured just as much as the served.
Ted Lasso. I have really liked it thus far. Its a contrived story about an American Football coach going to London to coach Futbol. He's a Quixotic character who sees victories in losing, progress in disaster, and humor in the humdrum. You root for everyone in this show. Its almost impossible not to. The Christmas episode in season 2 is some of the best, most uplifting TV I have seen. There is a reason it wins so many emmys. AppleTV+. You can see the first two episodes for free. And you'll likely subscribe after.
Better Things. Of the three, I least recommend this one. Not because of the content of the show but because it's not like the others. While there are continuing storylines through out the series (9 seasons I think), there are episodes where the storylines are not pushed forward very much if at all. Where the show runners actually drill deeper into a developed story line. Sam Fox is a single mother of 3 girls. She is a minor character actress who has some fame but is struggling. What I like about the show is that everyone is a source of friction. There are no gimmies on this show.
