I enjoyed it. The innerspace of the ship is so dumb but I don't really care. I was a bit disappointed Osyraa died. She was a pretty good villain when she was being pragmatic and not a cartoon character.
I really would love a reintegration of the Federation as the overarching storyline of Season 4.
I would like more time with Adira and Gray. They are underdeveloped as hell, and while I am glad they gave us Gray's story arc, I don't really feel I know him otherwise. And after resolving their being a joined human, Adira's only issues seem to be their use of pronouns, resolved instantly. Staying on that family, Culber's role is fantastic. What a shift from fridged love interest!
Stamets, however, is getting super tedious. Burnham and Vance were right. I find it so annoying that he's bitter about having to sacrifice. As opposed to most of the crew, he got to keep his family with him when coming to the future. He gained a bigger family there. Now he's mad at his commander that he almost lost them? I understand during the heat of it, but afterward? What an asshole. I guess that fits with his base character, though.
