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

6. Redemption, Redemption II

Sela steps out of the shadows. Data sticks it to Lieutenant Commander Hobson on the Sutherland. Enough said! Next entry. Naturally, there's more to Redemption and Redemption II than that — a Klingon civil war, funnelled and funded by the Romulans, and one half-Romulan in particular.

Klingon in-fighting (whatever next!) is not to everyone's taste. But even those with a blood pie optional palate must recognise that Redemption and Redemption II are objectively excellent. As well as letting us see parallel Natasha Yar's daughter, Redemption also introduced us to the famously boob-windowed Duras sisters. They were good fun, too, until they forgot to replace their plasma coils!
