- Best Known for the Fanservice: William Shatner's guns and Nichelle Nichols' abs of steel.
- Harsher in Hindsight: By the time Deep Space Nine rolls around, we get to see what Mirror-Spock's attempts at positive change have wrought, and it ain't pretty.
- 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.
YMMV / Star Trek S2 E4 "Mirror, Mirror"
