IMO, some of TOS episodes started out with an very interesting teaser introduction which promised that top rate acts 1-4 would soon follow. However, the main body of some episodes sometimes turned out to be somewhat disappointing. Which episode meets this criteria for you?
My choice: "I, Mudd". Even when I view this today I am enticed to believe that an excellent ST episode will follow the opening teaser.
However, I was greatly dissatisfied with the absurd story that comprised the rest of Stephen Kandel's script. Ugh!
