Star Trek: Every Two-Parter Ranked From WORST To BEST

7. Equinox, Equinox, Part II

'Equinox' or 'equal night' is more than just the name of the Nova-class, lending itself to the title of the two-parter. As Starfleet officers, and as Starfleet officers in similarly stranded situations, the abhorrent actions of Rudy Ransom and crew cast a long shadow over Voyager, too. There also, but for the grace of a bigger ship, go we.

As a set of episodes, Equinox and Equinox, Part II benefit from an absorbing, well-executed premise, backed by Jay Chattaway's heart-pounding score, and accompanied by an acting masterclass on the part of Kate Mulgrew and John Savage.

Janeway's 'dressing-down' of Ransom, and his subsequent attempt at a defence, was nothing short of exquisite to watch. And, whatever you thought of her methods, Janeway's determination to pursue the Equinox crew for their crimes was played to pitch perfection.
