Great episode to return to. I was expecting more focus on Una's trial, but I will gladly take a fun adventure with Klingons instead.
Good to see Lt Mitchell seemingly to get a bit of a bump in role. Though I hope they didn't get rid of Chief Kyle. I really need to know how he terrorizes ensigns.
The Klingon make up was great. I liked that they seemed to be willing to go beyond the hairstyles we've seen, and really expand on the forehead makeup. Still very much of what we think of as Klingon, but different.
I find it interesting that they seem to be focusing on the after effects of the war on the crew. Something covered occaisonally on DS9, but we also didn't a full post war season.
Spock as captain was great. Really needed to get that early practice in on stealing the Enterpirse. I do like that they gave a reasonable explanation on why emotions can kill Vulcans. Loved how he made peace with the Klingon commander. And then the hangover the next day was great.
The ship chase was amazing. Star Trek loves their outer space phenomina, and I loved those red crystal asteroids. Plus, nice seeing the old D7 again for the Klingons.
Chief Pelia was great. Look forward to seeing more of her. And already pre-installed reason for her to leave.
Great to have the show back.
