Si would have to venture a why to the success obtained by the fantasy world created by George LucasPerhaps this would be the easy external simplicity that covers the external complexity of the story. For instance, en Tattooine, one of the most underrated planets in the galaxy, the economic lag is mixed with a technological advance that exceeds our reality.
In the first movie the world knew about, we knew there was a Empire and one Resistance, a cluster of planets in which both factions were mixed … and that’s it. We did not know why the Rebels were fighting the EmpireBut they did and it was credible. We do not know what motives the Empire had for create a weapon capable of destroying an entire planet, but they did it and it was credible.
So fascinating was this world that the fanatics did not settle easily, or even with the rest of the trilogue, nor with later novelizations, nor with action figures that explained undeveloped parts of the plot, nor with the cmics, nor with the horrible Christmas special… they want to be ah. They want to live in that world.
