Born in '85, I grew up in the Star Wars resurgence of the 90s. Nothing compared to Star Wars when I was 8 years old. I loved Star Trek, but it was stodgy in comparison, and all the aliens were just different kinds of human stereotypes with bits of rubber on their face. It told interesting stories, but it didn't make me wonder what Crewman #4 went to do after his shift at the teleporter. That was the real power of Star Wars, the seemingly infinite number of weird creatures, bounty hunters, etc. who each had their own name and story to be told, it was a universe full of potential and might just be full of kids from nowhere like Luke (like me) who might one day find themselves with a lightsaber in the middle of a battle between good and evil.
So no, it isn't overrated. Star Wars is magic the likes of which hollywood has rarely produced. It's limitless space fantasy potential set loose in a child's imagination. I just wish the people making the movies these days could see it that way instead of feeling the need to add grit, deconstruct it, subvert it or make it "relevant." TPM(terrible as it may be in so many ways) and TFA(repetitive as it may be) are the only 2 movies of the 6 released in my lifetime that feel like they understand that core aspect of Star Wars. But ya know, they could make 10 more terrible movies and that original trilogy will still be pure magic.
