I used to like The Bill (https://en.wikipedia.org/wiki/The_Bill https://en.wikipedia.org/wiki/The_Bill), back when it had 30-minute episodes, each of which was in effect a self-contained little play using the same set of main characters.

Unfortunately, more recently, that's not what the market wanted, apparently.
