Star Trek: Enterprise, Series 3, Episode 18. First broadcast on Wednesday 3 March 2004.

This week, the Xindi and some big-ass lizard guy get to beat the crap out of (a) Enterprise and (b) Captain Archer, respectively. Meanwhile, Nathan and Joe are delighted, not because they’re mean (although they are), but because this is such a thoroughly entertaining hour of Star Trek: Enterprise. Who knew such things could be?

Star Trek: Deep Space Nine, Series 4, Episode 17. First broadcast on Saturday 24 February 1996.

This week, Miles and Julian learn about larping and friendship, Kira learns about clay and the inevitability of authoritarian male religious figures, and we learn about subtext and delightful character development — all thanks to Jane Espenson, who, it turns out, is the real hero of the episode.

Star Trek: The Animated Series, Series 1, Episode 6. First broadcast on Saturday 13 October 1973.

This week, crudely-drawn slow-moving simulacra of the Enterprise crew interact listlessly in a crudely-drawn slow-moving simulacrum of Star Trek. Except for the shapeshifting red octopus, which is awesome. Meanwhile, Joe drops £2.50 renting a Star Trek episode whose budget was nearly ten times that, adjusted for inflation.
