There were a lot of things that were predictable here. The race, Burnham finding the correct area, the priest having the ability to do things with the summit.
The episode description really gave away the answer... winning the race actually means you die for the people. (At least it wasn't another take on "Justice", which the description just sounded like.) But even without that, I already figured that was what the end result of the race would be... the story the priest told basically pointed a neon sign at that. When the end of something is telegraphed that easily, it's difficult to maintain interest.
Same with Burnham figuring out the moss. It dulled the edge, for lack of a better term, of what Tilly was doing.
The priest knowing how to use the lever and such is straight out of "THE PARADISE SYNDROME", where Salish said Medicine Chiefs carried the secret of using the obelisk and taught their children and so on and so on. Clearly, this is a not only a nod to that episode, but it's what Ravah will be learning soon.
I love how Rayner helped give confidence back to Adira. He's a very good leader... easy to see how he was a captain for so long.
Culber's story was nice, though I find it odd that the zhian'tara is what brings this existential crisis more strongly than coming back from death. His final scene with Book was really good, and I like what Book said about someone else not needing to understand your experience... it doesn't diminish what you feel.
Speaking of Book... it sure looked like he was playing Asteroids. Going old school... I like that about him, and I totally get it. I find more joy and fun from an old NES game than a vast majority of newer ones. They are called 'classics' for a reason.
This episode felt very much like it was from TNG or VOY, and that can be a good AND a bad thing. On the good side, those kind of stories were the meat and potatoes of the franchise. On the bad side, some of them could just drag on. I feel like this one did drag on a bit. I think the episode was a bit too long... which is in complete contrast to how I feel about streaming shows and not needing to adhere to a specific length of time for airing. The irony is not lost on me here.
Nice nod to Marina Sirtis, because I can't see any other reason why the Betazoid scientist would be named 'Marina'.
Kovich is always great to see. Could he be a Lanthanite? It would certainly explain a few things.
Three weeks straight of no Saru... that just feels wrong. At least we have an equally awesome character with Rayner.
One thing I did find irritating... they got the next piece offscreen. These pieces are literally a key component for the season, but they grab it offscreen? It gives the impression that it isn't important, despite the season (and the episode itself) screaming at the top of their lungs 'THIS IS REALLY IMPORTANT'. It messes with the overall tone of the season, in a very bad way.
I want to like this more than I do, but I feel that I can only muster up a 6 for this one... and I feel like I'm being generous.
