Stewart's portrayal of Picard did a lot to teach me what a wise, strong, dignified man looks like, especially in tense, difficult situations.
I know it sound silly to say that about a show with aliens, talking androids, and god-like beings. But I think that's what made the show special: it was able to be silly and campy, tickling that curious sci-fi part of my brain, while at the same time giving dignity to life and lifting my soul to be better.
