So, as I said yesterday, I am sick, and decided to retire early rather than watch the episode feverish. I did watch it this morning, but I'm still a bit off (mainly a pretty bad sinus headache) which may have negatively impacted the viewing experience.
Anyway, I really didn't like this episode. Easily beats out Point of Light as the worst episode so far this season.
First I'll give the episode some credit. I thought it seemed on a macro level well put together. While other episodes this season had fancy camerawork, fast cuts, and other distractions, the production itself was much more straight ahead this time around. And the overall narrative structure of the episode was pretty coherent, with the A plot (Tilly lost in the sporeverse) and the B plot (Section 31 crap) relatively tightly put together.
But, when you zoom in past the 5,000 foot view, it had a lot of issues.
Let's start with the main plot of the episode - the search to find Tilly, which also results in the inexplicable discovery of Culber. I realize that Trek is full of dumb technobabble, but this episode took things waaay past my suspension of disbelief. I mean, I guess I'm glad we didn't find out that all souls of the dead resided in the mycelial network, that it was just a one-time thing with Culber. But it was very clearly some sort of awkward retcon. The dirty, shaggy, half-mad Culber we meet is nothing like the serene spore-ghost we saw in the first season. I also don't understand how if real atoms don't exist in the mycelial network that Tilly, Stamets, and Micheal managed to - you know - breathe. Because my disbelief was never suspended, I simply couldn't emotionally invest in the reunion of Stamets and Culber, even though I knew it was supposed to be a touching moment. I suppose it was a nice Trekkian touch to have the "monster" be Culber - who was just trying to defend himself - but too little time was spent on this.
Regarding the B plot - the introduction of Section 31 to the Discovery crew - there really wasn't a plot at all. I suppose it's setup for later in the season and might develop some sort of payoff. But basically we see that Michael still doesn't like Georgiou, that Pike doesn't trust Tyler, and that Pike and Leland had some sort of history together. The last point in particular confused me, because through most of the episode they seemed like old friends who went down different paths, but then Cornwell dressed both of them down and said they had to work together??? They already were working together!
There were also macro problems with the entire episode. The dialogue was very clunky, dumb-sounding, and (things like Georgiou DRAMA aside) seemed to just exist to plot the plot to tech the tech. And the episode was framed with Burnham monologues on either side! Honestly I think part of the reason why I disliked this episode so much was because it had so much content which reminded me of the aspects of Season 1 I really didn't like.
