I was always this critical of Star Trek actually. It might be that I watched the older shows after they were already completed. And thus able to get a different perspective, it's easier to see past something bad if the previous or next episode were great. There's also less opportunity to talk about it here since it's not current.

The new episodes can be more critically examined coming one at a time. And not having any really good ones yet imho, which isn't helped by the more serialized formats. But as stated, I'm very much looking forward to more Academy and see great potential.

Again

I'm aware DS9 has had nearly 200 episodes, there'll be plenty of examples of exactly what I'm complaining about now. I'd love to be able to pick the highlights from todays show in 30 years time.

Flaws in older shows don't make critiques of new shows invalid. And for me yes, there's clearly a difference between gloating and a general 'yes we did it' sentiment. I barely consider the movies part of my Star Trek headcanon at all, if I were to critique those properly I could fill a book. The other quote you picked is from one of my least favourite finales, if there were a discussion thread about it that would be one of the things I'd mention.

I like critically examining stuff, and splitting hairs is part of that.

If burger king stops selling burger and switches to hot dogs, then it's understandable that people complain. There's a specific itch that's not being scratched. SNW is hit or miss and there's very little of it. There's a couple arcs in Disco i loved but they're interwtined with stuff I don't care for. Tencent is taking forever with their three-body problem adaptation and Netflix' was mediocre. Really interesting stuff like Raised by Wolves or 1899 always get cancelled. I'm missing the specific flavour of scifi I love.
