I feel like my biggest issue with Discovery was that it failed to live up to its potential. There was a lot that it did right and it had some interesting characters but it never really stuck the landing on it’s major arc premises.

The war with the Klingons was disappointingly handled. I find the little glimpses we get of it in strange new worlds to be way more compelling than the season that actually sort of focused on it. In addition to that the stakes were always way too damn high. Like every arc was an existential save the galaxy from war with the klingons, mirror universe invaders, or super AIs, or solve the energy problems of the future. The show also lacked that sunny optimism that trek normally has. Every once in a while it’d reach for it and then come crashing back down.

Overall it wasnt horrible but meh. When season 4 went on hiatus I lost track of when it came back. I meant to get back to the series but I just never mustered the momentum to do so.

I also feel like Picard was similar though I enjoyed the final season of that more(likely because it shamelessly tugged at my nostalgia strings.

With Strange New World and Lower decks the showrunners have found a better groove for trek I think.
