It was OK, IMO. For the most part, it did feel like a Trek episode, so they got that part right, as promised. It also felt like an expensive show, unlike this last season of Picard, which looked really cheap.
The ending was disappointing, though. Instead of a clever or drastic solution, it took only an inspirational speech. I was surprised that that was all that it took. I think that it would've been more interesting, realistic and powerful if they had continued their fighting. Every episode doesn't have to have a happy, ideal ending for the show to be optimistic, IMO.
Also, I could've done without a Spock love scene and yet another familiar name (Kirk). Speaking of familiar names, Noonien-Singh gave me Burnham vibes. I hope that that doesn't last.
Overall, I wouldn't say that it was good and it didn't exceed my expectations, but it was better than an episode of Discovery or Picard.
