The Ensigns of Command has always been one of my very favorite episodes. Dealing with a government that would use force to silent dissent because the position is irrational, Data does a great job of acting human to make a point. This also has my favorite Picard moment when he checks the plaque on the bridge for dust as he’s being hailed by the aliens who have been giving him a hard time. This episode is all Spiner, however, and he’s the best actor on the show.
