The writing is rough in this episode about a perhaps sentient comet that functions like a deity to those who choose to follow that line of reasoning. The story has the classic Trek underpinnings, but it needed cleaning up.
Issues we noticed were pacing, logic, and some skipped scenes. We spend quite a while with Uhura in exposition mode. Once the main problem with the comet kicks into gear, we have a strange visit from the comet's protectors. They seemingly pop-up from nowhere, so nobody noticed them at all on the approach? There's a few bits of information about how powerful these characters are, but then they're easily shutdown by the Enterprise, which happens to destroy the alien ship's weapons systems. There's no mention of this afterward. The aliens aren't at least grumpy about it?
The comet's innards attempts to kill a crew member and more or less succeeds. Uhura then has a musical chit-chat with the comet, but that never goes anywhere beyond her figuring out singing might do the trick. But what's the conversation about? That's skipped, and Uhura doesn't seem to entirely know what her singing did either.
Spock has a solution for diverting the comet's course, but we didn't know where it came from. The episode skips how the solution came to be, or maybe the Paramount app fritzed out, but either way we seemed to jump right into Spock making things right on the captain's order. Where was the planning scene here? It makes for a rough viewing experience without one, and that particular problem was prevalent throughout the episode.
