I've seen the entire Fandom In General change around me.
For 26 out of my 32 years as a fan, I felt like I was on the same page with the majority. Then Disco came and BAM! I was on the same page with people about Old Trek but not New Trek. Then ENT magically became beloved (kind of like Icheb!) and now I'm not on the same page with people about Old Trek or New Trek. Making it worse: People used to claim Gene's Star Trek ended in 1991, which I agreed with. Now it's claimed that Gene's Star Trek ended in 2005, which I don't agree with.
I didn't leave the Majority Opinion, the Majority Opinion left me.
That's how these things go, and I'm very glad they do. If people can reevaluate something years later because either they have changed personally or because they now value sth. more or less within a relative framework, it just means that the fandom is alive and not as entrenched in their positions as it often seems.
For me too, my fandom started waning after 2000: the latter seaons of VGR, then ENT (after the initial novelty value wore off), then DSC all struck me as "inferior Trek" when they were new. It was only reignited with PIC, LD, and SNW (to an extent). And because of this renewed interest, I started watching some of the shows I had given the cold shoulder to before. In that way, I've come to MASSIVELY reevaluate Voyager, which I now love as much as the other Berman Trek shows (it helps if you watch a show on its own terms, not in direct comparison to another show running concurrently, which was DS9 then), and my estimation of ENT has at least SOMEWHAT improved. Which means: while I currently dislike DSC with a fiery passion, that isn't to say that in the future I might not go back to it (I certainly will!) and then perhaps I will recognize things in it that, with some distance, then will register differently.
That was my whole point in initiating this thread asking about legacy. It's hard to say in the moment, but it might be fun some years down the road to go back to this thread, see what you posted about PIC and check if you still feel that way.
(Different franchise, but related sentiment: I might have to go and delete some of the disparaging tweets I made about Star Wars' Andor show last fall (or simply go by the old German saing "Was interessiert mich mein Geschwätz von gestern?") because it only took me half a year and one rewatch to recognize the brilliance of that show, which I simply didn't see during the first run. It can be that quick and simple.)
