I'm taking note of all these recommendations, as it looks as if we'll be mostly at home for a very long time! Here are some of mine:
My husband and I enjoyed all three seasons of The Detectorists (we had to pay for the third, but it was well worth it!). The characters are quirky and charming in the way that one only seems to see on British shows. The two main characters spend all their free time metal detecting...
We also worked our way through All Creatures Great and Small, which we saw when it first aired; it has not lost its appeal.
Recently, we finished watching The Good Place, which is one of the funniest shows we've seen in a long time.
Last fall, I watched Professor T. on Amazon, and enjoyed not only the very quirky characters, but also listening to the Flemish and relating it to my paltry German. I looked for other shows in Dutch/Flemish and watched Nieuw Texas, which was funny, but little slap-stickier than I usually like.
Currently, we have started Parks and Recreation, which neither of us saw when it was on network TV.
I've been watching a couple of Danish shows--on MHz Choice, The New Nurses (set in the early 1950s, when men were first admitted to Danish nursing schools), and on PBS Seaside Hotel. I think both are quite good.
