. . . it just throws this ep on the pile of 'bad Trek episodes', which is a shame, as it wouldn't have taken much effort to make the central conundrum the same without having such a contorted, hard-to-explain scenario at the core of it.
It is great fun. Cogley's overacting, his love of books, Finney's voice, "Heloo CAP-tain." Flawed, yes. Like me and many other things. But not a bad Trek episode in my opinion.
Peace to all.
