Some of my favorites on this latest watch-through (no particular order):
1. The Measure of a Man. An intelligent, high-concept episode with a lot of relevance to present-day issues. A lot more of these would come in later seasons.
2. The Royale. Cheesy and kind of stupid, but fun. Reminds me of a pulp 1950s science fiction novel. Or an episode of the Twilight Zone.
3. Q Who? Good action-suspense episode. Q is a great character when he's used properly, as he is here.
4. A Matter of Honor. Good Riker episode, good Klingon episode.
5. The Emissary. Some great character development for Worf and the guest star is really good in the role.
