No. The Showrunner changed. Every time Star Trek has a new Showrunner, the show changes to reflect their style.
It happened on TOS: Roddenberry --> Coon --> Lucas --> Freiberger
It happened on TNG: Roddenberry --> Hurley --> Piller --> Taylor
It happened on DS9: Piller --> Behr
It happened on VOY: Piller --> Taylor --> Braga --> Biller
It happened on ENT: Braga --> Coto
It's happened on DSC: Harberts/Berg --> Kurtzman --> Paradise
It's happened on PIC: Chabon --> Matalas
It's cut-and-dried: Michelle Paradise has a different idea for what she wants the show to be than Aaron Harberts and Gretchen Berg wanted. And Alex Kurtzman was a placeholder between them. Once Paradise took over, he went right back to focusing on The Franchise at large.
I'm not going to count Bryan Fuller because they canned him before production of the actual series even started.
Do I think fan reactions had
nothing do with the changes? No. But there were other factors at play that I think contributed to the change of the series more. If they listened to people
here for instance, nothing would ever get made because no one agrees on anything. And listening to people on YouTube Comments Sections is a total waste of time.
I miss the Season 1 feel sometimes, but I don't know if the series could run seven seasons like that. Everyone except Burnham would've been killed off by now.
If DSC didn't change, then I think I would've seen it as more of a "Do everything you can now while you can, because this might be the last season, so fuck it!" I'm pretty sure I said something similar to this in 2018. "Don't wait! Do it now! Go for it!" It was thrilling and exciting, and a huge "Fuck You!" to Berman Trek... but it was short. So we've exchanged "short & exciting" for "long & steady". I like both for different reasons but the thrill that was Season 1 would've been impossible to keep up.
