why are the first three movies of star wars have so much better graphics then the other three don't and way are don't they make a new one i felt that the last movies weren't that good at all.
Simply because the special effects in the latest Star Wars movies are far more advance compared to the first 3 Star Wars. George Lucas has said that he will never ever make another Star Wars movies anymore. The Revenge of the Sith was the finaone.
