What are your go-to comfort TV shows?

Let's hear it. What are your go-to comfort TV shows?

One of mine is BBC's Merlin (2008-2012) a British staple of the late noughties early 2010s.

But of course there are so many examples in British TV alone — and your answer could be from any sphere of era of TV, whether American, British, Japanese, or beyond. Whether in this century or the previous one. We all have a few shows that provide that comforting and nourishing effect!
