I also remember the Babylon 5 fourth season episode “Intersections in Real Time” as being particularly good.
I say that because its not just the episodes its self, which is brilliant, its the fact that by the time you get to that episode it really means something. There is a hell of a lot riding on the torture of Sheridan. The TNG episode, while in itself brilliant, sort comes out of no where.
(Yes, Babylon 5 is my Linux/Mac. Of course there is opinion to the contrary, but Im openly deaf to them.)
You just have to say "no, I won't" one more time than they can say "yes, you will".
