The Enterprise prepares for the evacuation of doomed planet Sarpeidon, but Captain Kirk (William Shatner), Mr. Spock (Leonard Nimoy), and Dr. McCoy (DeForest Kelley) find that all inhabitants have left via a time-travel device that has sent them to different periods of their own choosing. Kirk, Spock, and McCoy accidentally pass through the device, with the captain landing in the middle of an 18th-century-style witch-hunt while Spock and McCoy travel back 6,000 years to the Ice Age.

Fun Though Silly

I enjoyed the episode, even though it was unconvincing. There was no reason that Spock should have regressed to a barbaric state simply because he was in the past. His and McCoy's memories were intact. Since his memory was intact, all the training that he had gone through to suppress his emotions would also have been intact. It would have been more convincing if they had supposedly spent significant time in the past, and Spock, cut off from his civilization, gradually became more emotional. But the idea that he became more emotional because it was the past is absurd.

A minor point: Spock mentions that he is from a planet millions of light years away. Though the original series seems to imply that the whole galaxy had already been exploreed (as compared to just a segment of it as in Voyager), the Milky Way is approximately 100,000 light years. Spock's statement is way off mark, and not what we'd expect from the Enterprise's science officer.

That said, I enjoyed the episode anyway. Zarabeth is a really beauty, for one thing.
