That's Sub Rosa and Threshold levels of bad. I refuse to say anything else but: WTF? (At least the ice planet looks somewhat different from all other sets)
For sure not the best TOS episode. But it's also not the worst. The idea is solid - in a sci fi way of course. But some of the dialogue is weak. And the mechanical clicking sounds when Spock is moved are almost comical.

The story isn’t bad, but the script makes me understand why this episode gets the grief it does. I wonder if the novelization is better.
