Investigating the disappearance of Sarpeidon’s entire population just hours before it’s star going nova… Kirk, Spock and McCoy become trapped in the planets past…

The Trekzone Review

The penultimate episode of the original series was a welcome change from the long run of mediocre episodes that litter the third season. Spock and McCoy developed more on the friendship front in this episode than the whole series, the friendship that we see in the movies.

I think Spock’s interest in Zarabeth also helped soften our Vulcan officer just that little bit more.
