And you never will. The reason that the OT resonates with us all these years later is because Lucas immersed himself in the magic of myth, folklore and fairy tale. He studied the commonalities between the most enduring stories some of which were hundreds of years old still standing the test time. He never set out to make a 'Star Wars' movie; he set out to make a 'slay the dragon' quest and all the weird and wacky characters our hero meets along the way, using the old-timey serial format which invoked the stories that he grew up with as a child.
The original Lucas movies (including the prequels) were all about the story and the character journey and hitting the beats associated with that as opposed to familiar movie beats. That's why those films stay with us; they're more like bedtime stories and modern myth as opposed to movies trying to be 'cool' and 'badass' (which is arguably where the prequels fell down because he tried to incorporate cool movie moments into those which was a mistake IMO, even if I did enjoy them).
Now all anyone tries to do is make a 'Star Wars film' with none of those myth-making elements and they mostly end up being somewhat enjoyable but largely empty and flat. TLJ is the only new movie to even try to do something remotely interesting with the characters journey and the mythology and expand the universe in a meaningful way but everyone got mad so we'll get more safe-as-houses blockbusters like The Force Awakens or shallow fan-service films like Rogue One. The irony is that Disney was making Star Wars style movies that follow the heroes journey and fairy tale template for years in their animated division.
I love the new movies because, y'know, Star Wars, but I don't delude myself into thinking I'll ever get the same feelings as I get when watching the OT.
