The original trilogy lovingly evoked the classic sci fi and fantasy and space fantasy/space opera it was based and inspired by.
Things like E.E. "doc" smith's lensman saga, dune, lord of the rings, flash gordon via larry buster crabbe and alex raymond and al williamson, John Carter of mars series by Edgar Rice Burroughs and Tarzan.
the influences are endless.
if he was really trying to evoke milton's paradise lost he failed miserably. he seems to think he was doing a milton esque film with revenge see star wars in hell 60 minutes.
he seriously has to go back to college and learn how to write,LOL because he sucks.
even the pulp fiction and dime novels of the early twentieth century and the depression era movie serials which are today viewed as rubbish that star wars was based on were written better.
