However, I don't think that being "more in tune with the 80s/90s/00s Trek" is in and of itself a marker of improvement. I don't like the idea of being tied down to that particular time of the Trek franchise or holding it as some kind of golden standard. They should always strive to improve rather than being stuck in the 90s.
That's exactly what worries me about this season. It feels more consistent than the first season, but that seems to be almost entirely because where season one was constantly smashing the accelerator and trying new things, even when it'd be better served by coasting a while and letting what it'd already done unfold naturally, season two is pumping the breaks, putting out a lot of crowd-pleasing fan-service to cram the show back to a late-Berman-era "TNG-lite" mold. Captain Pike, the show becoming all about Spock (like, seriously, to a "When Poochie isn't on-screen, other characters should be asking 'Where's Poochie?'" extent), forcing the recurring cast more to the forefront because on Star Trek, the bridge crew is definitionally the most important group of characters, and smoothing down everyone's personality into a blandly professional agreeableness except for explicitly plot-derived conflict or wacky guest stars. I worry that the ultimate destiny of DSC, and the other CBSAA Trek shows, is to be an inoffensive hour-ish block of Star Trek-flavored video content that's just good enough to keep people spending their ten dollars a month until, as with Voyager and Enterprise, people eventually get tired of intentionally-generic Star Trek and tune out, and the franchise goes on another hiatus. DSC doesn't necessarily need to be good to survive, just good enough to keep you from remembering to cancel your subscription, and while that kind of safety should be conducive to boldness and innovation, it doesn't seem to have been so far.
Star Trek shouldn't be so, well, self-consciously Star-Trekky. There's a way of making this a Star Trek show without just throwing out a lot of pop-culture Star Trek talismans at the screen like the Prime Directive and Mr. Spock or, God forbid, half-assed "issue" stories.
However, one area where I think the show should take a look backwards towards the '90s (and, for the matter, towards the '60s) in its second season is in character scenes. Not even, like, whole unrelated b-plots, just a little downtime, like the TNG poker nights or something. Everything this year has been rush, rush, rush, plot, plot, plot, drama, drama, drama, and it feels like there's hardly been any room to breathe. They could uncram the plots a little bit just to give everyone a chance to sit with the problem, or even talk amongst themselves about stuff outside of work, without continously blasting through the episode like a bunch of ping-pong balls in a dryer.
