I should add that saying Star Wars is much easier than saying “Star Wars: The original one from '77”, and gets the point across just as well.
But that’s the problem, it doesn’t. 99% of the time (and slightly less of the time here but still a larger percentage of the time) it doesn’t clarify which Star Wars you are talking about.
I support calling it Star Wars to make a point, but I don’t do it because it takes too long to clarify.
