@J0E, to answer the first pair of comments first, you said:
The only difference is when we saw the movies. That’s it.
That’s not entirely true. Context matters (more, maybe, with some media—and movies—than with others) and can’t be ignored.
When my dad went to see WW II films in theaters, we were still fighting that war. He might watch the movie with every expectation that “the good guys will win”, but overriding that, he had next to no real idea how the war itself—a hugely more important event!—would turn out.
When I watch a WW II movie, I might hope from an entertainment / emotional point of view that “the good guys” in the movie come out on top, but more important than that, the war itself was won by “the good guys”. So the context is turned around; the ‘context’ in which a WW II movie (from before 1945) mattered a whole lot more than the movie itself, because that ‘context’ was—my Dad’s own life. When I watch the same movie, thirty or more years later, it’s pure entertainment, and nothing more.
I’m not saying that Star Wars, or any movie, really, has great significance all by itself, but you should attempt to understand the context that made those movies so popular at the time. Just as I might watch a WW II movie right now and see “pure propaganda” (and you could watch Star Wars and see elements of the same), it’s the context that makes those films relevant.
Most WW II movies—and Star Wars—today are no more than moderately entertaining without their cultural context.
I’m not going to—can’t even try to—judge “how big a fan” you are, but unless you either lived through the time (and paid attention then) or can grasp the relevance that the movies, or books, radio shows, plays, etc. had for our lives at the time, then you’ll be missing something.
To put this into more perspective, read or watch a production of The Crucible, by Arthur Miller. Here’s a play that is set hundreds of years ago. It’s pretty much just entertainment, with a message, yes. But when you examine the history of the USA at the time this was written, it carries a whole new import that today’s viewer probably doesn’t get. (Though maybe a bit, since the PATRIOT Act and other such foolishness. One can only hope.)
What you might view from the past as “cool; very entertaining” ... was our lives.
