Undiscovered Country is even better if you watch it in the original Klingon.

I’d put it above all the TNG movies, too.

I can understand why. The motivations and message are a bit deeper than WoK. But UC wouldn’t have happened (in the same way) without WoK first, since I don’t think Kirk had the same hatred towards Klingons before. Distrust sure, but not revenge level hate.

UC also has that connection with one of the best TNG episodes, Yesterday’s Enterprise.
