Episodic TV basically burned me out from when I first started noticing such things, about twenty years ago, or so. It's a little thing, but it adds up to a reminder of "Oh, this doesn't really matter" or "That character was important."
I'm not up to speed on the latest TV, largely because it doesn't appeal to me. And part of that is growing up with episodic things where it didn't matter.
I mean, I'm not a big TV watcher either, but everything I've seen in the last decade other than The Orville has been serialized. Absolutely everything. Which is really tiresome, because sometimes you want to have a short story instead of a novel, and there's benefits of doing the "anthology with a fixed cast" thing that Star Trek, the X Files, and other shows in the past did so well.
I recently watched a podcast where they interviewed Ira Steven Behr of DS9 fame. At one point he talked about how there are fundamentally two different kinds of stories - plot-driven stories, and character-driven ones. He said he finds plot-driven stories functionally speaking kind of boring, because there isn't much depth beyond "this happens this week." and always tried to keep DS9's focus on the character growth and development. While a completely procedural show robs characters of the ability to grow, a completely serialized one makes them "slaves to the arc" in a certain sense, often reduced to implements to move the grand plot of the season along.
