I think the main split in the Trek fandom now is how serious a tone people tend to prefer. Most of TNG was professionalism porn, and most of the 90s stuff was generally serious. A lot of people got used to that, and whenever I talk to them about stuff like SNW or LD, their chief complaint is that “the characters act immature and are too quippy”. To an extent, I can agree and see the point of view, but on the other hand, I really like it when Trek doesn’t take itself too seriously.
I like to argue that the TOS era was a less mature era of Starfleet in general which causes the familiarity with the bridge crew to be more socially profound as opposed to professionally based. To whit, I remember SNW directly addressing things like this wherein they discuss “General Order 1” being renamed “The Prime Directive” which I feel is evident of a maturing organization.
Strange New Worlds doesn’t take itself seriously unless it has to. It’s been great about totally experimenting with the Trek formula to create unique, fun and memorable episodes. The plot devices are straight out of the 70’s, with random space anomalies impacting the crew. They modernize the storytelling and keep up the pace, which is always just what the TOS era needed.
