What is the most underrated episode of TNG?
My vote goes to "Lower Decks". Very compelling story, and the poker game scene is amazing. "The First Duty" comes in second, despite Wesley, wih great performances by Ray Walston and Robert Duncan McNeill (a pre-Tom Paris role as a sleazebag).
I believe the character of Cadet (later Ensign) Sito appeared in both episodes.
