so let me preface all this by saying two things real quick:
1. i am not a nostalgia junkie and i don't cling to things and want them to be a certain way because "that's how they used to be" and,
2. i understand the marketing angle to brand recognition and why you'd want to slap a known property name onto something to get instant consumer appeal.
so here's the thing:
star trek was a show with a theme for a very long time, and that theme had to do with the utopian future of the human race, of mankind coming together and becoming better than our base and petty earth-bound animal history.
if you map it out broadly the 4 primary series (TOS, TNG, DS9, VOY) each had an arc which worked within the theme.
in TOS you had a sort of gritty frontier vibe and while the crew sometimes squabbled they were always trying to come together for the greater good, this is like the 'growing up' stage of the dawn of human utopian civilization, working out the kinks but it has a plan and it's working towards it.
in TNG you had the more mature version of this vision, the crew never quarreled with each other, everyone worked together towards one goal.
if you look back at how much of TNG was diplomatic missions and the central conflict being negotiation and conflict resolution it's kind of astonishing.
DS9 was where the ideals that were first striven for in TOS and attained in TNG were challenged - where a largely secular body had to deal with a deeply spiritual culture, of racial strife, of war... DS9 had a much grimmer tone but at the time it was the outlier of the franchise, it was meant to be darker and antagonistic because it was acting as a crucible for the ideals set up within the series.
VOY was similar, but instead of having those ideals directly confronted it examined if those ideals held up in a completely detached and alien environment, finding out if you can hang on to your principles devoid of the context in which those principles were formed, and how you have to compromise in order to survive.
the big problem with the ST franchise overall within the scope of its media presence and place within the popular culture is that the movies post Generations totally lost sight of any of star trek's themes or understanding of action being a contrast to idealism, and just made ST another sci-fi action popcorn flick, and as they went on they kept getting dumber and dumber.
first contact is a giant ball of utter horseshit, insurrection and nemesis were utter dumpster fires, the reboot was like 1 ounce of potentially decent idea mixed in with 97 gallons of hot badger piss, into darkness was possibly the worst movie i have ever seen in my life, and i never saw beyond because fool me twice go fuck yourself.
anyways, the point of all this long rambling crap is this:
ST: discovery isn't star trek in any sort of thematic way, nor in any recognizable story sense.
it's just "generic space war bullshit show #915" but with the name 'star trek' slapped on it to try and fool people into watching it, because god knows there isn't fuck-all in the show itself to merit enough interest to pay for yet another subscription service.
