Overall I liked the episode a lot. Saru's death stuff didnt go over for me at all. He knew it wasn't under normal circumstances. He also knew it was forced by the sphere. I would have expected him to be fighting this artificial state, not surrendering to it. OTOH, of course its not simple to suppress X millennia of genetic programming... I also thought it was a little quick for them to be immediately interpreting the data dump to get Spock's course... But hey, its the universal translater. OK, and I thought that was a horrible idea that people's speech would be changed by corruption of the universal translator. I think that concept had more holes than a wheel of swiss cheese. It makes the universal translator worthless if you can't turn it off. And TOS never had it in user hosted form where it could do that. Again, something where people couldn't say "No, this is wrong it wouldn't work that way".
