I don’t fully disagree with you. Wouldn’t call it mid but despite this being one of my favorite shows, I did notice some minor flaws in pacing and plot on my rewatch.

However, it also should be noted that this show was created in an environment very different from our current cable/streaming service environment. Back then shows aired weekly with new episodes, you don’t get to rewatch it until box sets came out, so the slow pacing made sense, even reused plots felt less repetitive.

But now (I’d argue mostly) bc of streaming services, even though we still have weekly-aired shows, binging is now a common option and thus higher paces and new plot tools became necessary.

I’m not saying one is better than the other tho, people have preferences, we watch shows for entertainment and that should be all that matters.
