You're repeating yourself. So I feel compeled to repeat myself. The "value" of Trek history, as you characterize it, really doesn't exist. Trek history was used as a weapon against ALL of the spinoffs, including TNG and DS9. But in fact, ALL of the spins have made use of the franchises' history to varying degrees, just as various member s of the fandom used that same history to point out the shows' supposed shortcomings.Well, my point about 50 years of Star Trek is that they have that vast canon to draw on.
They know what works, what doesn’t work, what’s been done to death, what’s left to explore, etc.
So based on that rich depth of data, I would have expected the story to have been more cohesive.
They used that history as a club at least until those folks realized that they liked what they were seeing. Of course, this didn't occur until 2 to 3 seasons into the shows. Sound familiar?

But it’s early days. Maybe comparing it to a show like the flash or supergirl would be more like-for-like in the modern era:

Well, you're twisting yourself into a pretzel trying to bring to some sense to a position that makes no sense.As for expecting us to know as much about the characters in only 15 episodes compared to 70-odd, I would have thought that comes down to the writing as much as anything else. With a good writing team I don’t think that it’s impossible to expect parity with something like TOS
There is no way a showrunner would tell his/her audience that after the first 15 episodes of a show, that you now know everything about our characters as you could know in 80 episodes of a show. This, to you, would be good writing?

No TV writer would do this. It makes no sense, and you wouldn't like it if a show did do this. Or IDK, maybe you would like it. In season 4 of Ent, the writers let us know something about Hoshi Sato that we had never before been told. There were some fans who complained about this.
In other words, those few fans, apparently, not only thought they knew everything there was to know about Hoshi in the first 80 episodes of Ent, they were annoyed that the writers chose to write something new about Hoshi. I take it from your statement above, you would have been among those fans. What you suggest, would lock the characters forever more into who they were in the first several episodes of a show at the expense of character development and any (Hoshi-like) surprises for later seasons.
I don't think this means what you think it does.- but there I go holding DSC up to a higher standard again![]()
