I don't agree. I found the tonal shift a bit forced. I don't see the necessity of changing the series' tonal shift. I want "Star Trek Discovery", not some borderline copycat of "The Orville". Not even your typical Trek series from the past had such a drastic tonal shift.
The introduction of Anson Mount as Christopher Pike contributed to this tonal shift. His Pike came off as slightly bland and at one point, I found the character's regret for not participating in the war against the Klingons as not very interesting. And why is he a regular on this show? Why is he even a regular for Season Two? He and his two Enterprise officers, along with Michael Burnham, had succeeded in their mission, they should have left. Either Discovery would have found itself with a new captain or Saru could have become its permanent captain. Frankly, he deserves it. Instead, Kurtzman drummed up some lame reason to keep Pike around so that the show can have some bland white guy as the main authority figure in order to soothe the nerves of those fans who could not deal with the chaotic Gabriel Lorca as captain or Michael Burnham as the show's lead.
I blame the fanboys who want the show to recapture the past. And I blame Alex Kurtzman for listening to these fanboys, instead of basking in the success of Season One and moving forward with more innovative stories. It's just a crime that producers like Kurtzman, the Warner Brothers suits and Kathleen Kennedy are so afraid of the narrow-minded fanboys that they would rather keep their respective franchises either mired in the past or borderline bland. And in doing so, they end up ignoring the fact that when these franchises were innovative, they were also box office or ratings successes.
I have come to the conclusion that part of the Trek fandom, like the ones for other franchises, strikes me as rather frustrating and narrow-minded. These fans would rather cling to the past, rather than enjoy something different or innovative for its franchise. And when show runners like Alex Kurtzman kowtow to loud and rather conservative-minded fans and critics, entertainment and art in pop culture becomes in danger of declining into a sad affair.
I'm not surprised that you would save your biggest complaint about her. She is still portrayed by a black actress. Perhaps you'll become a major fan when the show puts a white man in the lead.
