Problems
- Giant Spock...

Factoids
- This episode was written by Walter Koenig, who played Pavel Chekov on TOS. It is the first Star Trek production to be written by a Star Trek actor.

Remarkable Scenes
- Kirk: "Beam us up, Scotty!" Another very close line to the famous and much parodied but never actually uttered, "Beam me up, Scotty!"
- Spock reciting the philosophy of the IDIC.
- Kirk: "Any chance of teaching me that body throw?" Sulu: "I don't know. It isn't just physical you know; you have to be inscrutable." Kirk: "Inscrutable? You're the most scrutable man I know!"

My Review
This episode is completely pointless. It tries to make a point about how creating a master race is bad, but the ridiculousness of the plot blasts away any profound messages that it attempted to convey. We're not given any explanation for why Keniclius or Spock were so huge, the plant aliens were interesting but ultimately served no purpose, and Keniclius' goal of creating a peacekeeping army was pointless seeing as how starfleet is essentially just that. In the end, Keniclius gives up way too easily; or should I say not soon enough because his motives were so blurry? Only small details in this episode redeem it, such as Spock's recital of the philosophy of the IDIC and the reference to the Eugenics war of 250 years ago.
