2x01 - Brother: One of the best season openers since DS9 in my opinion. It basically felt like what a 21st century Star Trek movie should be, a perfect action-adventure piece to set up the seasonal arc. It had just the right mix of humor, thrilling action, mystery and character drama, and was also the best imaginable introduction to Pike's character.
2x04 - An Obol for Charon: One of the best of DSC ever, what at first seemed like a revisit of the classic man against the machine plot akin to TNG's Contagion, DS9's Civil Defense or Voyager's Worst Case Scenario turned out to be an intriguing and surprisingly uplifting, true sci-fi story about the Sphere wishing its life's work to go on. The episode caused me my first tears shed in the season, at the conclusion of Saru's plot and at the Sphere's self-sacrifice. Not to mention Tilly. She was an absolute delight in this one (and the next one as well - these two were easily Mary Wiseman's best of the season), and she broke my heart with Space Oddity.
2x08 - If Memory Serves: It was a perfect homage to The Cage. It started with that beautiful recap which ended with that insanely powerful, brilliant cut from Jeffrey Hunter to Anson Mount with the same expression on their faces, and it just went way up from there. I can't find any problems with this episode even if I tried.
2x09 - Project Daedalus: I liked it much more than Frakes' other direction in the season; it felt more mature, collected and professional than the first seven episodes. I know many felt the focus on Airiam was rushed and undeserved, but for me it built her up perfectly to the point I actually cried for her at the end. This was also the episode where I finally realized how much I identified with Burnham, after already finding her very relatable in her interactions with Spock. Their heated argument in the middle of the episode, especially Spock's scathing criticism of Burnham's chronic hero syndrome and ingrained self-blame was a cathartic strong point in her arc.
2x13 - Such Sweet Sorrow, Part 1: A beautiful and strong build-up to the finale. Not only did it feature a gorgeous Enterprise that felt like coming home and a wonderful return for Tilly after being reduced to a gimmick in the second half of the season, it had many beautiful emotional moments centering on the others' decision to go with Burnham, Pike's final address to the crew and their farewells to their families. The whole episode was one uninterrupted moment of tense, excited anticipation for the finale. In retrospect, I had to coclude I actually liked it better than the finale itself... If Parts 1 and 2 were considered one episode though, I would include them together.
