Star Trek discussion /usually/ tends toward anything new being bad, and always has. SNW and lower decks are exceptions because they do so much fan service and return to a more classic Trek format. Discovery was groundbreaking in a way that I’m sure Roddenberry would have enjoyed, but groundbreaking also implies jarring change and throwing away things that work for experiments that sometimes don’t.
It mirrored the contemporary idea of the “End of History”, where all the existational crises were done with, the federation (was basically moving into a time of refinement rather than having to worry that the experiment might still utterly and completely fail. TNG was basically one long, slow lesson of why that was a flawed notion. You don’t build a cruise liner, fill it with families, and then intentionally send it into the kind of peril that regularly befitted the Enterprise D. In retrospect, it was completely ridiculous.
