“Whom Gods Destroy” *
Kirk and Spock are held captive by an insane former starship commander with designs of conquest.
This episode does have occasional small moments in it, but it is a truly sad affair to see TOS sunk so low. And adding add more insult it looks so cheap. The costumes look like remnants from a stage theatre trunk. There is practically no set decor except for the station's control room. I cannot recall seeing such a barren and sterile looking set. The sets of "Spectre Of The Gun" and "The Empath" are fucking brilliant compared to what we get here.
Although it's quite a dark moment the method in which Garth kills the Orion slave girl Marta is coldly effective. And Steve Inhat is rather convincing as an unhinged personality veering wildly from lucidity, delusion and mad raving.
There are also some ludicrous ideas in this. Only a handful of incurably insane individuals left in the galaxy?

I don't think so. A far future psychiatric facility that looks to have more in common with a 19th century prison?

A planet wide forcefield to keep inmates in and can also withstand a starship's phaser barrage.
I think there could have been a story in this, but it's just so poorly executed as to be embarrassing. "Spock's Brain" could be considered a four or five star compared to this.
There is a reference of interest in this and it's a shame it isn't elaborated upon. Listening to Kirk talk about Axanar one could be led to believe or at least wonder if he's referring to the founding of the Federation. The whole spiel of leaders and statesmen with a dream that becomes a reality and makes Kirk and Spock brothers. Hmm... If so then it would go someways to explaining away the early references to earth vessels and colonies as opposed to Federation ones, all because the Federation would only be about fifteen to twenty years old. Hmm...
