As you know, "Turnabout Intruder" turned out to be the last TOS episode to make air. I personally feel that the series could have gone out on a better note.
With that in mind, which third season episode do YOU think would have made a better finale?
I'd go with "All Our Yesterdays". Not only do I feel that this is the best episode of season three, but it would make my top ten episodes of ALL Trek series.
What about you?
