I find "Requiem for Methuselah" a mediocre episode of Star Trek (1966-1969), but one enlivened and even made bearable a beautiful, even poetic ending that brings into clarity, again, the friendship between Kirk, Spock and McCoy. Before the beautiful (and emotional ending), the episode depicts a thoroughly unbelievable love story for Kirk.
