ST TNG S5E07 + 8: Unification 1+2
Pretty ambitious pair of episodes, bringing in Spock and dealing with matters galactic - involving Vulcans, Humans, Romulans, Klingons and Ferengi - among others. We have Riker playing detective AND keyboard virtuoso, a swan song for Sarek, and the rather fantastic trio of Spock, Data and Picard - imagine if that trifecta went on to more adventures?
And Sela, daughter of Tasha Yar, up to her shenanegins - with a particularly weak takeover Vulcan plan.
There's numerous good scenes, a few clangers and some great ones - often whenever Picard is on screen, or when Spock and Data interact. Standouts are the scene between Sarek and Picard, the brief scene between Data and Spock talking about humanity - Nimoy was amazing with his few lines - and the final scene between Picard and Spock where they mind meld.
