The way I see it, Star Wars simply did what rock bands have been doing for years. Someone mentioned that heavy metal didn’t exist when Black Sabbath emerged. That’s true of so many bands. What the hell was KISS? Glam? Metal? Neither - they were just KISS. What were the Chili Peppers? Funk? Nope. Punk? Nope. Rap? Uh-uh. Just a weird mix of lots of stuff. I’m pretty sure Kurt Cobain didn’t say one morning “let’s invent a thing called ‘grunge’ - I’ll call up Chris Cornell and Eddie Vedder and we’ll start a movement”. Nirvana didn’t do anything new, but they certainly were unique.
Star Wars is Star Wars.
Except Lucas copied more than 5 established science fiction properties, all space opera, to base Star Wars on. Complete with sword fights, other primitive weapons, blasters, space ships, evil tyrants, advanced mental powers, stories of good vs. evil. characters you could call wizards, princesses, emperors, evil henchmen, aliens, and pretty much everything in Star Wars. He brought in Campbell and the samurai code, but that wasn’t all that unique, only how he did it. Heinlein would call Lucas an engineer - taking things that already exist and putting them together in a new way. The genius lies not in pure originality, but how well it resonated and became so popular. So Star Wars wasn’t doing something new and different. The comparison to something that was new and different doesn’t apply. It’s more like Star Wars is the 57 Chevy of movies. From a long line, but something was different and unique that made it extra special - just not something truly new.
