Star Trek: The Next Generation, Series 6, Episode 9. First broadcast on Saturday 14 November 1992.

Data is excited to get a new puppy and understandably miffed when Riker decides to explode it in order to solve this week’s space problem. Back on Earth, Nathan is delighted by the story’s optimism and sheer nerdery, while Joe remains sceptical.

Star Trek: Voyager, Series 2, Episode 18. First broadcast on Monday 19 February 1996.

Opinions are split on this week’s Untitled Star Trek Project, with Nathan leading the prosecution and Joe the defence. Will Nathan sentence Death Wish to be imprisoned a comet, subsisting only on a rare form of Nogatch hemlock? Or will Joe prevail with the argument that at least it’s Voyager trying to have something to say and giving John DeLancie a new thing to do?

Star Trek: Lower Decks, Series 3, Episode 7. First broadcast on Thursday 6 October 2022.

This week, a mathematically perfect recurring villain gets her own episode of Star Trek, and we discover how much fun the show can be without all that relentless moralising, just moments before we also discover how much fun it is to watch a villain get her comeuppance while some dunderheaded bird people shake off the dead shackles of a stupid tradition.
