The season 4 trend is a very slow, gradual, barely noticeable creep upward. Each episode gets just a little better. So, this was my favorite one of the season, and the first to break the "8/10" barrier.
It still feels like a run-of-the-mill TNG episode (as did last week), so I'm conflicted. But, the story on this one was tight and it is elevated by the guest cast, who were all tremendous.
PROS:
1. The Risa Scientist Guy was fantastic. It's always fun when they have strong egos and personalities to bounce off of Reno and Stamets.
2. The Prison Guy was straight out of a TNG episode, but he was pretty awesome.
3. I liked getting back to the anomaly. The experiment was fun and interesting. Obviously, it's Nagilum or V'Ger.


4. We finally get more of Culber and Stamets together.
5. We didn't have to gut through any of Adira and Gray
6. Vance had some more time, as did Big Glasses Guy played by Famous Director Dude
7. Burnham telling that Magistrate to go crap in the warp core at the end of the episode was fantastic
8. Saru being Saru....love it.
CONS:
1. I'm tired of Book being a baby.
2. I'm not surprised or wildly disappointed, but I was hoping the DMA would be a naturally-occuring phenomenon
3. I miss Tilly, but in all honesty, this episode felt tighter and more focused because without Tilly, Adira and Gray, they could focus on 4-5 main characters and the 2 key guests, and it felt much more natural and cohesive than when they try to give everyone something to do.
4. I've started to dread the obligatory Michael and Book scenes. I can't explain why...but I wish they had made a different choice here other than "let's have the captain do missions with her boyfriend rather then members of the crew"
5. I can't come up with a fifth thing right now, other than maybe...as much as I liked this....it still has drifted so far from the earlier DSC tone and so far toward "wanna be TOS/TNG" that I both love it and hate it simultaneously for that.
Overall, a highly competent and fairly entertaining hour of television...but nothing overly engaging or super-exciting. Elevated to an 8 purely on the strength of the guest cast and the absence of A and G this week.
EDIT: My biggest worry is, if they are going with this "episodic problem of the week overlayed on a light serialized storyline" format (which it seems they are)...what happens when SNW comes on the air and is basically exactly the same thing? I thought the whole idea of multiple shows at once was to have them all be distinctive from each other in significant ways. DSC S4 has felt more what I would expect SNW to feel like.
