All Eyes on Me

I liked that the characters don't change, for a while. It's okay to make a show whose main plot is that the characters can't change. The problem is that we got the point by the end of season 4, and subsequently the show jumped the shark. Instead of having a wrap-up season 5 showing Don not really having changed and maybe Pete and Peggy starting to turn into Don, they prolonged it for 2.5 more seasons. (I have not seen any of the second half of season 7.) Sally has been the only interesting character for a while now, because, as far as character development goes, the adults are so unchanging it's basically episodic. The story arcs repeat as in a conventional episodic show, except they're a few episodes each; at the scale of 2.5 seasons, it's just as episodic, just slower.
