I did laugh at the repair bots on the Enterprise hull.
@guyute03 My first thought was R2 as well!
Anyway, that episode was a bit, well, wow.
Despite the story stagnating a little for a few episodes, I felt the Red Angel story actually tied itself up neatly enough. The sight of the Kelpians and the Klingons warping in to save the day was a brilliant moment. The fact that it was all down to Burnham's actions in travelling to the different systems in the first place really clicked for me.
Today is a good day to die! That almost made it worth having the badly paced Klingon arc this year by itself. Almost. I am happy that Tyler hasn't travelled to the future with Discovery, so hopefully it's a bit of a reprieve from this useless guy.
Poor Admiral Cornwell! I's convinced myself a while ago that Pike was going to end up in his chair by the season's end, so I was happy to see him lie another day. Now with a shaven Spock, they can bring on the Pike series.
Discovery travelling to the future, only for us to not actually seeing anything happen there, was probably a wise choice. It left things mysterious enough for us to wildly guess everything that will happen next season. With so much going on in the rest of the episode, just making it though the wormhole felt like an epic farewell to the crew.
I also liked that we haven't had a reset button at the end of it all to explain why Burnham was never mentioned in TOS. Yes, a bit of hand-waving going on, but I liked that Spock, Pike and everyone else lied about Discovery's whereabouts, and that because of the failure of Section 31, Starfleet should keep it classified.
