TNG - Unification, Part II was such a missed opportunity. It's kind of depressing, really. It was so filled with corny cliché and was so obvious, from the first, what was going to happen, as soon as Spock meets with the Pro Council. The sets, the costumes, the makeups were all on the cheap and this distracted from Nimoy, quite a bit. Unification, Notice how Nimoy never did come back for further adventures. Notice that. How TNG could've dropped the ball, here, is problematic and puzzling. It may have had to do, in part, with the necessity of tying the adventure in to The Undiscovered Country, directly.
Had this not been so, at the very least, Romulus may have not ended up on Spock's itinerary. But ... all of that popcorn was at stake, so ... we get an episode that's passionless and pointless. Pointless because Spock hasn't gotten anywhere with Romulan leadership when the show started and when the show ended? He's STILL not gotten anywhere! WTF? Just hateful, all around ... when a fan could write a better show than what the 'professionals' dish out, that's bad. That is so bad ...
