It was a breath of fresh air after the disappointment of Discovery and proof that there are people who still believe in Star Trek’s optimistic vision of the future. I think for that reason I and many other fans gave it a pass for a lot of it’s flaws.
My biggest problem is that I feel the social commentary is rather poorly done. I’ve gotten into some nasty fights on reddit for saying so.
I’ll start by saying what I think it does well. It’s good at humanizing people who live in an oppressive society and portraying their point of view.
But the ideas it discusses aren’t especially original or insightful. The world building doesn’t exist to support them. The Moclans might be a fine allegory for trans and intersex issues, but they only work as an allegory and make no sense at face value. And they’re portrayed inconsistently to allow whatever kind of episodes the writers want.
I feel like one issue is that McFarlane does not share the ideals of Star Trek. I don’t get the impression that he sees the value of non-interference, for example. But nevertheless, the Union believes in it because the Federation does. Politically, he’s a more conventional thinker than the classic Star Trek writers.
