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.
