1/2
The best thing here is the location photography: SoCal aerospace office plazas make for a good outer rim science colony. I totally dig it. This is the one where these flying jellyfish hit Spock in the back and give him crippling and debilitating pain. And where we learn he has an “inner eyelid” (but forgets to tell anyone, so we can all think his light therapy made him blind.) I dunno. This episode is okay.
