What I’ll never understand is how someone can find a story as “rich”, “expansive”, and overall “emotionally satisfying”, a version of the Star Wars universe where:

The main character’s parents were people that we’ve never seen or met, and will probably never get to see, barring prequels.
The princess character belongs to a family that (thanks to the Death Star) we’ve never met, nor whom we will ever learn about in potential sequels.
A solitary knight(Ben) with no family or progeny whatsoever.
A villain who for all we know is some one-dimensional guy behind the mask. Nothing to his past, other than having once been a student of the solitary knight character.

That’s the character dynamics of the stand-alone Star Wars film, in a nutshell. I can’t see a story with such characters going beyond a single film.
