I thought they were going to kill off both gay characters in back to back episodes for a minute there.
I got really annoyed with the hacky cinematography reusing the exact same zoom into the ship from outside trick being used like 3 times within a very short span of time. WE GET IT. FANCY CGI.
The Andorians looked ok. I wish they'd resist the urge to add random shit on the face every time they bring back a race, but at least they were instantly recognizable unlike the Klingons. I think the other guy was a Tellarite? Looked ok. They were never a featured race anyway. Did they even appear after TOS with that budget mask?
Really lame making the emperor that awful actress from the first couple of episodes. Not just because of her shitty acting, but because it makes the whole thing feel small and narrow. What a coincidence the emperor of the entire Terran empire happens to be one of the closest people to Michael and also bringing back a dead character. Yawn.
Not sure how I feel about mirror universe Sarek and his goatee. Pretty cheesy giving every evil Vulcan a goatee, but then again the entire mirror universe is cheesy at its core.
That said, these last two episodes have been more passable than the first half of the season, at the very least because there's less established in the mirror universe for them to shit on canon quite as hard.
