A great line from that episode is when Apollo says something along the line of being a god and Kirk replies “We have other gods now.”
Always liked that show as Kirk or Spock referenced that maybe these aliens were the basis of “gods” in ancient times - an echo of von Daniken, et al?
Felt kinda sorry for Apollo when he realizes that Game Over has occurred and wants to join the old gang.
Like others, I prefer the original series with all its corny sets - at least some of the aliens were in non-human form instead of just humanoids in different configurations.
