Robert Bloch, the sf&f writer who also wrote Psycho wrote this episode. This episode aired on October 27th 1967 and back then tv shows would have a holiday episode for Halloween, Thanksgiving, Christmas and Easter. For the most part, these kinds of shows couldn’t be accommodated on a science fiction series like Star Trek but for some reason they went out of their way to make this travesty.
The Enterprise is exploring a lifeless world. Sulu, Scotty and a red shirt have fallen out of communication on the surface. The red shirt calls to be beamed up and when he appears on the Enterprise, he drops down dead. Now a “spooky” voice tells the Enterprise that the planet is cursed. Kirk, Spock and McCoy beam down and find a silly Halloween set. There is a castle complete with skeleton filled dungeon, black cat, witches and fog.
We meet a wizard, Korob and his familiar, a black cat who is also a “beautiful” woman named Sylvia. They have captured Sulu and Scotty and zombified them. Eventually they zombify McCoy. They can play tricks like taking a little model of the Enterprise and holding it over a candle to make the real ship start to overheat. We find out the aliens are creatures from another galaxy and of course they don’t have emotions or other fun stuff so Sylvia makes a play for Kirk. Kirk pretends to like her but she figures out he’s faking and gets angry. Now Korob frees them from the dungeon and nervously tells them that they must escape because Sylvia has gone nuts and will destroy them all including him.
She turns into a giant black cat and hunts down and kills Korob by smashing him under a dungeon door. As he’s dying Korob reveals that the source of their power is a magic wand. At the key moment Kirk smashes the wand and everything returns to reality. No castle, no fog and Korob and Sylvia are now these little six-inch figures that look like they are made of colored pipe cleaners. Scotty, Sulu and McCoy are unzombified and unaware of what has gone on. Then they go back to the ship.
Even back in 1967 when I was ten years old, I knew this episode sucked. It has nothing. They couldn’t even give us a really good-looking woman with not much clothing. It was all bad. It isn’t even redeemed by Shatner mockery points. It’s a waste of time except as an anthropological study on early television holiday tie-ins. I give it a 3 // 1.
