Picard is super relevant, though. If we're talking about an alternate reality where Picard S3 never happened, then yeah, I'd agree that complaints about nostalgia are a little over blown. I don't see why that would be a discussion worth having, though. Picard did happen, and so did a whole lot of discussion about a possible Legacy show, and if you're wondering why you hear complaints about nostalgia, that's a big part of why.

That's not the entirety of it, though. Outside of Picard, I'll say that Strange New Worlds and Lower Decks absolutely trade heavily in nostalgia. I can't agree with your view that either don't count. Having a fresh style doesn't change the fact that SNW is set on the classic Enterprise and is continuing to introduce more and more classic Trek characters. And Lower Decks built a whole episode around the reuse of a specific cave set from TNG, of all things. A huge amount of its humour and appeal is definitely based in nostalgia.

I will say that it looks like Starfleet Academy on a good course to do it's own thing, Picardo notwithstanding, so I'm not saying the franchise has gone completely bankrupt or anything. I just think there's enough nostalgia going around that it's pretty valid to feel a little put off by it if one is so inclined.
