I liked this one a lot. It was very different for DSC, and I almost felt like I was watching what TNG or DS9 would have been if it were produced in the modern era. In that way, I found it absolutely fascinating to watch because, even though I enjoyed the pervious seasons of DSC very much, I always wondered how good the show could be if it tried a different pace, style and tone. This was certainly a departure. Even the directorial style was understated.
Again, that's not to say I don't like the more upbeat, high-tempo style...but I just liked this as a breath of fresh air. The character beats and relationships were spot-on. Past Trek would have had everyone smiling and moving on after having leaped 900 years into the future....but here we get to see real, lasting impacts to people. Burnham's shift in character is amazingly effective and SMG is a radiant and magnetic presence more so now than ever before (although I do wish they had presented the delta in years to be more like 3 rather than 1...but hey....who's counting?). And, I do love that we spent a considerable amount of time on an alien world, learning about their culture and their status and finding our way through that puzzle. Adira is an absolutely fascinating character, and the performance is also very good. I also loved that Hugh Culber and Keyla Detmer got some meaty stuff to do. Emily Coutts is actually quite talented...and has been painfully underused.
Also- this episode was amazingly scored. The music absolutely helped sell this episode.
I've honestly got to put this one up with Context is for Kings, Into the Forrest I Go, New Eden and If Memory Serves as another great moment for the series.
I'd give it a 9 for story, but when I factor in all the intangibles (score, direction, acting, and the tonal uniqueness for a DSC episode)….it elevates it to a 10. First 10 I've given since If Memory Serves...and well earned.
