Star Wars first came out in 1977, all of the tropes and story beats and iconic figures were completely unknown to the world. It's easy to take that for granted, especially if you're a big nerd in your early 30s and the lexicon of Jedis and the Force and lightsabers and whatnot have been a part of your DNA since you've been in diapers.
Anyway, it'd be cool if I could go back to that time before I knew every single second of the original trilogy backwards and forwards. I'm sure that's true for other people for a lot of things; the joy of discovery is what makes us go out and see new bands, or try new foods, or go ziplining over a pit of venomous alligators.
