1. A dark, gothic sci-fi mood that still feels striking
Even among early TOS episodes, Exo III stands out. The USS Enterprise enters orbit, and we drop into a world of underground caverns, bizarre machinery, and eerie, echoing corridors that feel more like a haunted castle than a sleek 23rd-century outpost.
The pink-purple lighting, huge sculptural doors, and looming android Ruk, portrayed by The Addams Family's Ted Cassidy, turn the whole setting into a kind of sci-fi Frankenstein lab where something clearly went wrong a long time ago. That mood holds up in 2026 because it’s so specific.
This isn’t another beige soundstage planet. No, it’s a hostile, alien interiority that mirrors what’s happened to Dr. Roger Korby (Michael Strong). He’s literally gone underground and surrounded himself with perfect, emotionless constructs. In an era where a lot of genre television tends toward samey digital backdrops, the handmade weirdness of Exo III still pops.
