I just finished the series yesterday. Season one and two are weak as fuck and don’t feel like star trek at all. Its ok as a random explode-y sci-fi show though. Seasons 3-4 really did feel like star trek and I liked them quite a bit. One of the best parts of the show is all the main characters have a lot of growth through out the show and its done in great realistic way. The ending of season 4 was awesome and up there with some of the best trek episodes.
