One of my earliest Trek memories is going to see Undiscovered Country in the theater, which about coincided with the time when I started getting into TNG. Looking back I can't swear which came first.

There's plenty of mockable stuff in TOS, but it was the 60s so yeah. I probably should give it a chance but I'm a TNG-DS9 person, kind of like I'm a New Who person, TOS and Classic Who just aren't the same thing.
