As much as I loved its first season, I have to say that this season far surpassed it and any of my expectations. I was particularly pleased with their willingness to take chances with episodes like the wonderfully hilarious crossover with the Lower Decks cartoon series and the highly entertaining musical episode. These lighthearted shows helped break up much darker and serious episodes that dealt with the loss of loved ones and post traumatic stress disorder.
While I'm not a fan of cliffhangers at the ends of seasons (even though Star Trek shows have a history of them) nor some of the strange coincidences on which weaker writing often relies, I still enjoyed the concluding episode for this season. I had been concerned that the writers were going to "fridge" a couple of characters [killing off characters (particularly female love interests) as a motivation for main leads to take action] in this finale and was glad to find that I was wrong (although it is still a possibility for the next season's premiere). Instead, the plot went in directions that I did not expect but still felt (mostly) believable.
With the writers' and actors' strikes and the studios' ridiculous refusal to meet their reasonable requests, there's a good chance that I will have to wait longer than a year for the third season to be made (let alone come out). It's going to be an uncomfortable amount of time to wait. I might need to hold more than one "marathon" to keep me satiated until then.
