Star Wars is by no means a revolutionary story. George uses scores of literary tropes and cliches from Luke’s Heroic Journey to star crossed lovers and betrayal of brothers; the list is endless. So with this many obvious plot devices, how is it that Star Wars has become the absolute behemoth it is today? Lucas was able to capture the imagination in a way that allowed the audience to imagine themselves as their everyday style heroes. What makes the characters in Star Wars great is less about their fighting prowess (as amazing as it can be) and more about how they, as ordinary people, rise to do extraordinary things.
Lucas brilliantly included an array of characters anyone could relate to in a universe detailed enough to imagine yourself in and that is a large part of why his stories are still being written about and expanded upon.
He truly created another world in a galaxy far far away.
