Old favorite TV show is holding up in rewatch

[Skywatcher]

Here’s a related thread from last month:

"Perfect" television shows

What shows do you consider to have been perfect? Not just good or even great, but perfect. Please use spoilers where appropriate! Some criteria (in my head). No growing pains, the show hits the ground running from the first episode. A satisfying series finale, even if the show itself was strictly episodic. No “dud” episodes. Even the weakest episodes are still good. No “gollum” scenarios where the show lives much longer than it should have There are lots of excellent shows that aren’t perfec…

“Barney Miller”, mentioned there a few times, holds up for the most part. There are a few dated references, like the Pope being Polish.
