Star Trek Retrospective: Episode 33 Mirror, Mirror
This is one of those episodes that I both love and hate. I love it for being a brilliant episode with a cool story and Spock with a beard. Plus Uhura in a skimpy outfit and Terra kicking ass like I wish they would. I love seeing evil Spock and all his logical glory.
On the other hand I hate this episode for being the standard go-to inspiration for every single series. In any of the following series when things get slow and uninspired at the writing desk they just take a trip to the Mirror universe. TNG, DS9, and Enterprise all did it. Voyager managed to avoid it (I think) but honestly how would the Borg of the Mirror universe differ from the ours? Perhaps they assimilate with flowers and religious pamphlets?
The other part that bugs about the fact that every show has to visit the Mirror universe is that if there is one parallel universe logic tells us that there have to be literally billions, and finding that one specific universe is nearly impossible. Also, what is the deal with Mirror universe having to be evil? It’s like when Kirk got split in two in The Enemy Within. How did he split into good and evil halves? Couldn’t he just split into gay and straight, or the half that is OK telling the world about his toupee and the half that wants to keep it hidden? Does the Mirror universe have to be the evil reflection of our universe, or could it be the version where the Smurfs had a massive resurgence in popularity in 2173 and now everyone takes descriptive names like Brainy or Hefty (or in the case of most red shirts Deadsy. Odds are Kirk would have gone for Sexy although he might have been cool with Papa).
