“Why is Star Wars not science fiction? “
In science fiction, by definition, one fundamental aspect of the universe must be different from our real universe. The plot must hinge on that difference. Without the different rule or law the plot will not work. You might point out The Force, but it is just a plot tool, not a fundamental difference without which the plot won’t work. Star wars is High Noon in space.
“Star wars is High Noon in space.”
Good analogy.
Star Wars is poised to become a genre of its own.
