It's funny how one's views can alter over time, even on trivial matters. I used to enjoy Star Trek, although I wasn't really a Trekkie (perhaps a Trekker). In the '80s and '90s, used to read the novels as they came out -- some were excellent, some only fair (not surprising as there were many different authors). But gradually I tired of the whole Star Trek universe and for many years I've had no interest at all in re-watching the old series from the '60s. Lately some switch flipped and now I'm enjoying them, even being well aware of their flaws. Somehow my perspective changed. Just in time for social distancing.
I sort of get what you're saying. I watch modern Star Trek and feel it has descended into a darkness and a grimness I find at variance with the original series and Roddenberry's vision. Some true believer trekkers get snarky when I say that. I don't care. The original series posed that we were a better species dealing with the challenges of the trek out there. The new series see us as the same backbiting, backsliding and backstabbing people we are now, with a few 'heros', but surrounded by 24th century toys. Never forget, ST is not made by idealists like Roddenberry. It is made by studios with complex and insidious connections to the US military industrial corporate security complex, which has its tentacles in every facet of US news, TV, movie, and all other areas of entertainment and information services. Everything you watch in mainstream media in America is part of the manufactured consent and public discourse control exercised by the power elites who run the country, and for whom mainstream information and entertainment instruments ultimately serves. That includes Star Trek, and hence the dark dystopian themes they peddle now suits perfectly that manufactured consent, as Noam Chomsky, brilliant analyst of US power structures oft says. It's only entertainment, but I for one never forget what's really going on when I watch TV, movies, news and the rest, including Star Trek.
