I just found the discussion on it. Apparently the terms were not used much out side of star trek and was too much a ymmv, which is true, however most people agree on certain quality issues for various plots within trek and a few other ensemables. The problem is it's subjective based on ensembles. I am thinking about digging out a new version of this by a new name and making it a trivia. I think the problem here is those of us who like subjective are being out voted.

I agree that Good Troi Episode should be its own trope. A Day In The Limelight is an episode focusing on a minor character. Good Troi Episode is a good episode featuring a usually-boring major character.
