YMMV / Star Trek S2 E4 "Mirror, Mirror"

• All There in the Manual: According to the Star Trek Concordance by Bjo Trimble, the Mirror Universe version of McCoy is a sadist who runs his sickbay like a torture chamber. He is also described as sullen. This may be from the original script notes.
• Best Known for the Fanservice: This is the episode that introduced the concept of a Mirror Universe, but the thing most anyone remembers strongest - besides inventing if not codifying the idea of an Evil Twin having facial hair because the Mirror Universe's Spock has it - is Uhura disguising herself as her Mirror counterpart by showing her abs. Even people who are into guys could probably remember it best as the episode in which Captain Kirk bares his arms and shows off his guns.
• Harsher in Hindsight: By the time Star Trek: Deep Space Nine rolls around, we get to see what Mirror-Spock's attempts at positive change have wrought, and it ain't pretty.
• Heartwarming in Hindsight: Considering how violently xenophobic the Terran Empire is depicted to be in Star Trek: Enterprise and Star Trek: Discovery, it turns out to be really significant that Mirror Kirk and Spock have a genuinely respectful relationship.
• Hilarious in Hindsight:
  • Mirror Sulu's lecherous interest in Uhura. It really is a mirror universe, Ohhh Myyy!
  • Prime-Spock's comments about easily spotting the Mirror landing party are darkly hilarious after watching Star Trek: Discovery.
