That was lovely. Not an absolutely perfect episode, not an all-time classic, but one which perfectly encapsulated so much of what makes Star Trek work, from exploration of relatable human conditions to cooperative problem-solving.
This was, of course, an "Uhura episode," - and Celia Rose Gooding shows yet again her ability to carry a scene despite being the youngest member of the cast. The decision to weave her unresolved grief involving both her parents' offscreen death and the very onscreen death of her mentor, Hemmer, was inspired, moving me close to tears at one point. However, it was also an effective ensemble piece. For many episodes this season, one or more of the characters were simply missing or effectively absent from the narrative, but here, everyone is given something to do. For the most part, all of these threads work as well, other than the Una/Pelia subplot, which seems out of left field and left me kinda cold with its clearly manufactured drama.
Of course, the episode cannot be discussed without considering the return of Paul Wesley's Kirk, as he's effectively co-lead here, in his third appearance on the show, but first actually playing "real Kirk." With every reappearance, I find myself warming to him. He's a complicated character, walking a fine line between being arrogant and empathetic, in part reflecting his younger age at this point and lack of command experience. While we never saw Uhura and Kirk interact in a significant way in TOS, Wesley and Gooding have good on-screen chemistry, and their dynamic together helps to center the episode. I adored the scene with Kirk, Sam, and Uhura brainstorming a solution within Sam's laboratory. Plus, we get the canonical introduction of Spock and Kirk!
If there's one issue I had with the episode (other than the manufactured Una/Pelia drama for the sake of a B plot), it's that everyone goes along with Uhura too easily in the 11th hour. Pike's a mench and all, but he's destroying a major bit of Starfleet infrastructure on the word of an ensign that it's all been figured out, with no corroborating evidence. No command structure in the world would work like this, and it wouldn't have taken more than a few additional lines to "fix" the issue via some technobabble regarding having the ship detect the aliens.
Other than those two things, almost a perfect episode of Star Trek, highlighting all the strong points of this show.
