My expectations for this one were low based on the preview, but I enjoyed this one more than I thought I might. A very "traditional" Star Trek plot in many ways.
Watching the Culber/Stamets interactions, I wonder if they're going to address the "awakening" that Stamets had following his genetic modification. That's something that's been mentioned a bunch of times (as recently as two episodes ago), but I don't remember them ever digging really deep into it. It seems like there are some parallels there that could be explored.
One day, I'd really like to get an oral history of the making of this show, particularly those tumultuous first two seasons...
