I waited for my son to be home from college before watching, and we just finished.
So many scenes of DS9 touched on the nature of heroes, of legends, of inspirations. Li Nalas, Akora, Michael Eddington, Kor, ... even Sisko himself.
This episode understood this, and it was suffused with this search for figures, for role models, that can shape your life. The facts don't entirely matter.
It touched on how difficult it can be to live in service to one's community, one's country, the pain that it can cause, and still the opportunities for happiness.
It touched on the euphoria of learning new things and integrating them.
And it showed how a power fan can effectively Mary Sue her way into her favorite series.
My son gave it a 10. I'm rounding up to 10, but not that much.
