The question is, if Star Wars never existed, what would "we" be into? Aliens? Battlestar Galactica? Harry Potter? Predator? Buck Rogers?
This is a silly nonsensical illogical question, because if Star Wars wasn't made, then neither would most of the Sci-Fi that followed. But just for fun, assume that everything would have happened anyway even if Star Wars never was. What movie and/or movie series would have grabbed the likes of us? Any of them? None of them? Was Star Wars that unique?
