Mnay people complain that a Top 10 list of episodes is simply too limiting since they may have 12, 13, 14 or 15 first rate TOS episodes. For this reason, I decided to post a list of top 14 and bottom 12 TOS episodes. My top 14 episodes are: The City on the Edge of Forever, Space Seed, The Trouble with Tribbles, Mirror Mirror, The Doomsday Machine, The Devil in the Dark, The Enterprise Incident, Journey to Babel, Amok Time, The Ultimate Computer, Dagger of the Mind, The Tholian Web, Balance of Terror and A Taste of Armageddon. Meanwhile, my list of the worst 12 Star Trek episodes are: Spock's Brain, The Way to Eden, The Omega Glory, And the Children shall Lead, That Which Survives, The Alternative Factor, The Gamesters of Triskelion, The Mark of Gideon, Miri, The Lights to Zetar, Plato's Stepchildren and Let That Be Your Last Battlefield. "That Which Survives" was acted and put together so poorly that its no wonder Robert Justman left season 3 of Star Trek after this episode. Two strong Star Trek episodes in my view are “Day of the Dove” where we see how compelling Michael Ansara played the role of a ruthless Klingon leader and his wife, Mara, who is actually a scientist--and the real ‘dove’ of the episode and “Obsession” where Kirk's leadership abilities and judgment are called into question by his officers when he pursues an energy entity at the risk of delaying the delivery of badly needed medical supplies. But they aren't in my top 14 list unfortunately though I'd certainly recommend them. But what is your list of top 14 and bottom 12 TOS episodes?
