I have a feeling this might be no small part in why TOS and TNG are the two ST series that contain 90% of the "only comes up once" sci-fi plots / concepts / worldbuilding that people ever make reference to when talking about "things from Star Trek" rather than when talking about Star Trek. TOS and TNG, while definitely soft sci-fi, were to some degree trying to create 22-minute-long works of literary Speculative Fiction, modelled after the sort of things you'd read in serial SF magazines of the 1950s. Later ST series are emphatically not that, and nor do they try to be.
But as you said, I think it ends up with a higher quality show.
An annoying facet of ST episodes is the morality lessons they push, like on every episode of The Brady Bunch.
While established SF writers wrote episodes for the original series (Harlan Ellison, Theodore Sturgeon, Theodore Sturgeon, Norman Spinrad, etc.), David Gerrold was a recent college graduate and "The Trouble With Tribbles" was his first sale.
It’s nice to watch something that highlights the best of humanity in a future setting.
Almost everything else in SciFi is dystopian. But ST is a rarity. And it’s all the more beautiful for it.
The difference was that rather than turn it into soap opera porn, the characters actually tried to behave professionally (most of the time).
• DS9 only had a little soap-opera drama, serving as almost a kind of fanservice sprinkled judiciously into otherwise-thematic B-plots.
• VOY had more, with entire B-plots of episodes now being character-focused, including a few arcs that would have worked just as well if transplanted into some modern-age military drama with no SF elements.
• Drama-as-the-A-plot episodes were appearing by ENT.
(After that I stopped watching, but I've heard the trend has just continued from there.)
But when you only have half a dozen-ish episodes per season, you can't afford filler.
It’s such lazy writing.
I actually didn’t mind Academy. Yeah it was flawed and had a lot of lazy tropes. But it had an identity to it and some substance to it. Not much substance, but still something. Whereas the latest season of Strange New Worlds? It wasn’t anything. It had no substance. It had no identity. It was as if someone made a silly clip show (like the Stargate 200th episode) but instead of lots of short parodies in one filler episode, they made an entire series with each episode being one very long joke. A singular punch line stretched out over nearly an hour.
I hated the first season of Discovery. But that was still better than the season 5 of SNW. I hates the first season of Enterprise. And that was also better than S5 for SNW. And I wasn’t much keen on the first season of Lower Decks either. And even that was less goofy than S5 of SNW. And what’s worse, all of those spin offs that I said had poor first seasons ended up with excellent 5th seasons. And yet SNW started of strong and fizzled out it shallow jokes.
It honestly feels like the writers had nothing.
I really enjoyed TNG as well, and DS9 probably wouldn't have even happened if not for TNG's excellence. I never really felt like the writers gave Picard's character a lot of room to change, though. A lot of the time, he was almost like the sitcom dad who was mainly there to teach the kids a lesson at the end of the episode. That's not a knock on Stewart's acting ability; I'd say he was almost certainly the best actor on the show.
Also agree about Bashir.
And some of O'Brien‘s best performances were counterpointing Bashir too.
I think as a solo character, he’s a little shallow. But he works exceptionally well at being an anchor for other characters to play off.
But yes, those instances were a bit rare.
