I think that, since 2009, Star Trek has become too much like comic book franchises, in the assumption that it is not so much about ideas, as iconic characters. Both Discovery and Picard have suffered from this; Disco through defining Burnham through her relation to Spock, then recasting Sarek, Spock, and Pike, among others; Picard though Picard himself, the many returning characters, and the focus on Data's legacy, all at the expense of the new characters, the Romulans, and any new civilisations (it's the first trek show without any new species among the regular cast).
Historically, Star Trek was always more about ideas than characters. That was how it could come back without recasting any of the original characters, and periodically give us a whole new cast again in the same universe. Had it taken the 'comic book' attitude earlier, there would have been no Picard, just various versions of Kirk, Spock, and their crew.
