I thought the Melkot's test was quite poor. (That was Doohan's voice by the way) It reminded me a bit of "The Savage Curtain" which actually came later. I thought an "Arena" like test would be better. You see the "You did not kill?" is an interesting topic. It did not come out that well here. It's almost like the whole OK corral thing lead the script instead of the idea and lesson of the episode leading the story as it should have.
