The last season is the best season, but that's not really saying a lot. They didn't know how to write with all the constraints of canon and (spoiler alert) ended up throwing the ship the furthest into the future of any Star Trek show by centuries. Once they could ignore all canon (everything was so far back in time so as to be irrelevant), it got okay. Not good, just okay. But at least not terrible.
Anyway, there are some likeable actors and a few likable characters, (I love Michelle Yeoh and Jason Isaacs, and Saru is the best), if you care for that.
