Spock: There are ancient Earth legends about wizards and their familiars.
McCoy: Familiars?
Spock: Demons in animal form sent by Satan to serve the wizard.
Kirk: Superstition.
Spock: I do not create the legend, Captain. I merely report it.
As the others have begun the discussion, let’s get going on this week’s episode, Catspaw! I’ll begin by saying that historically, I’ve never been a big fan of the whole “planet of the [theme]” thing, whether that theme is Nazis, gangsters or ancient Greek gods. It always seemed like a letdown, like filler between more epic and interesting episodes - you know, like last week’s “Doomsday Machine”. But in this case, we do get a pretty interesting and kind of fun episode.
For one thing, it’s at least not as dumb a concept as “aliens find a book about Halloween and decide to build their culture around it”. In this case, the aliens have powers of the mind, and in their attempt to probe the Enterprise’s conscious minds instead tap the subconscious and access the primal fears of the crew. Now they’re a little bit silly, what with apparitions of witches and black cats and such, but you can at least see how they got from point A to point B.
For another, there is an interesting power dynamic between Korob and Sylvia that I didn’t really pick up on so long ago. And the idea that Sylvia, experiencing physical and emotional stimulation that she has never experienced before and going a little mad, does make sense as motivation. And while Kirk does express one of those typical seduction of the alien things, he recognizes that his only shot may be to overwhelm her with the sensation that she is seeking. It may be a stretch to call it clever but, as I mentioned, it does at least make sense to the story.
A few things I have to call out as pretty strong elements - first, really impressive face plant fall from the actor playing Jackson after beaming back onboard the Enterprise. That looked like it could have really hurt. Also, I think the cat actor did a pretty good job. OK, they were probably just luring it around the set with toys and treats, but at least it did hit its marks. Last - the episode was written by Robert Bloch, who is a legend of horror and science fiction writing. It’s a return engagement for him, as he had previously written “What Are Little Girls Made Of?” which as I recall we all thought was pretty decent.
