I think more people would be upset by GL's death then you reailize. He did create a film that redifined film making. Lots of directors followed GL's example and created great films.
However, it is true that GL didn't take more time into creating the PT, should've had Irvin Kershner do AOTC. At tleast the love story wouldn't be so corny.
But, you will fine that there will be many that follow his vision and redifine film making in some way.
You'd actually be surprised about how many PT fans i know of...
