Every so often, these adaptations are more sexist than the original episodes. I’m almost impressed that Blish managed that with Spock’s Brain (an episode I happen to enjoy a lot, for all its many, many flaws). Some things are just better off barely stated in dialogue, rather than expanded on in longer form. The descriptions of people generally in this series are quite dated, and it’s strange to see where the TV show holds up while prose versions don’t.
