1. Tapestry - The good side of Q and I love the story. 2. Q, Who - The tough love side of Q and the only instance I can think of where crewman die becasue of his actions. 3. All Good Things - The show begins and ends in the post atomic horror court room. I love the final speech from Q to Picard.
"Tapestry" -- just a great character episode. "Q Who" -- The second sign that TNG was going to be something more than warmed-over TOS and a great showcase for the "dangerous" Q. "Q-Less" -- By this point I was getting sick of Q and loved seeing Sisko punch him in the face.
