It was OK, IMO. For the most part, it did feel like a Trek episode.
The ending was disappointing, though. Instead of a clever solution, it took only an inspirational speech. I think that it would've been more interesting, realistic and powerful if they had rejected it and continued their fighting. Every episode doesn't have to have a happy, ideal ending for the show to be optimistic.
Also, I could've done without a Spock love scene and yet another familiar name. 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.
