I haven't felt that. If anything, I feel it's a spectrum. Some love TOS. Some are indifferent to it. And some feel it's problematic as hell and like every instance where there's a revision that "corrects" it.
Controversial opinion: I always break down the different eras of
Star Trek and fans' reaction to them in Biblical terms, which I guess is surprising for a franchise that's atheistic.
- Old Testament: TOS, TAS, and to some extent the TOS cast movies. TOS is the basis from which all Star Trek originates. It has elements and ideas that are really, really interesting and evocative that have become standards by which every iteration of Star Trek tends to use as a baseline. And it also has parts that are very weird and strange when compared to everything else. Just like how people tend to forget the parts of the Bible where we're supposed to stone someone to death for planting different crops side by side or working on Sunday, most fans just ignore the goofy parts like "Spock's Brain" and exact duplicate planet Earths ("Miri") that exist because of ... some reason.
- New Testament: The Berman era of TNG, DS9, VOY, and ENT. I'd argue TNG is an evolution of TOS in the same way the loving God as benevolent father in the New Testament is a shift in tone and vision from the wrathful God as divine judge from the Old Testament of the Bible. The rough edges of TOS are worn away for a more idealized Utopia in TNG that offers a message of universal acceptance and salvation through the underlying values of Trek. Both VOY and ENT reinforce those ideas, positing Starfleet as a force for good that exemplifies how humanity and ultimately the galaxy will be brought together through science, technology, and tolerance. DS9 in many ways is akin to the Apostle Paul's letters where he's trying to give form and meaning to the message. DS9 fundamentally wants to believe in all of the things that Picard gave beautiful speeches about, but understands that trying to apply Trek's values in the real world goes beyond just a speech.
- The Book of Mormon: The Kelvin Universe and the Paramount+ shows. Mormons consider themselves Christians. They believe in the crucifixion, resurrection, and divinity of Jesus Christ. But many Christians don't believe Mormons are a "real" denomination of Christianity because of the additions they've tacked on within their dogma. Ever since 2009, all of the new Star Trek offerings still are based in the ideas of TOS and the original elements of the franchise, and there are fans who love what's been done. But a small but significant minority of Trek fandom look at these films and TV shows as basically the equivalent of Joseph Smith claiming to be a prophet of God and saying he found gold plates with additional material to the Christian God's message. It's story additions that are either argued to be tangential, wrong, or not accepted as something that should be incorporated into the canon because they're not "real" Star Trek.
