This super-advanced race of airheads with a teaching machine that can transplant knowledge far ahead of anything the Federation has seen somehow
can't figure out how to design a simple thermostat. And only a brain of Spock's caliber will suit. (Forget trying the writer's brain.)
Then there's the matter of one of the three inhabited planets in the system (remarkable all by itself) experiencing an ice age, while the others are not. Must be those carbon footprints, or something. "Cave men" wearing button-down shirts along with their furry boots. Ad nauseum.
No, it's not that bad. It's far worse. This episode is like one of those pain belts.
