I thought Chain Of Command was a bit rubbish.
It's a straight lift from Nineteen Eighty Four it's not even a variation on the same theme like Babylon 5's Intersections In Real Time, it's the same scenes with almost the same words.
And that awful incidental music, and the make-up.
For me the best Next Generation episode is Yesterday's Enterprise.
Proper science fiction and a sense of urgency that was sorely lacking from most TNG stories.
I really liked the weird one with the masks, I wish I could remember what it was called... does anyone know the name of the TNG story with the masks?
I liked the one where Troi turned into a cake and aliens stuck probes up Riker's beard.
