This is one of those episodes that require us to accept an alien force that has capabilities to withdraw sense from a human. It's one thing to be a vanguard for populating another world (much science fiction and especially The Outer Limits hangs on this possibility. When the alien come to the desperate scientist, who is on the verge of a nervous breakdown, one can understand that he would do what he could to gain access. But the fact that an interplanetary culture has no knowledge of emotions but has the ability to absorb someone else's, makes everything more fantasy than sci fi. The story is a pretty good one. Ikar comes from a beehive culture, not unlike the Borg from Star Trek: The Next Generation. Every entity has his or her own purpose. When he ingests the emotions of the scientist and goes about testing out his newfound toys, it becomes really sort of silly. I decided to let that go and evaluate the story as presented. It is suspenseful and interesting and maintains the attention. It is heavy handed with a kind of human proselytizing, showing how superior we really are. Television in the sixties couldn't seem to shake this sermonizing.
