I really don't have a problem with people who enjoy the PT. I think the problem is how Lucas treats the OT. Historical revisionism is a trait that I cannot abide in anything, let alone in a pop cultural phenom that is the original Star Wars trilogy.
I know a lot of people who are not a freakishly into Star Wars as myself (not a huge nerd like me) who hated the PT, yet who still like Star Wars. All the revisionism is tarnishing any respect for Lucas from the non fanboy public. There was a time when Star Wars was cool, everybody knew and talked about it. Even in the so called dark ages of the late 80's and early 90's, it was still relevant in all the kids I went to school with. We may not have talked about as much as when we were in grade school, but every time we mentioned films that we liked, the OT always was near the top. The new films never resonated with the public. The PT made a lot of money because they were fricking Star Wars, everybody had to see them, even though they disappointed the majority of the film going public.
There is nothing wrong with being popular. The Beatles are still remembered as being one of the greatest bands of all time. They were extremely popular in their time, as well as such artists like Louis Armstrong, or Frank Sinatra. Regardless if you like their music or not does not deny them of their influence on their contemperaires, or the musicans who followed.
I believe that in the future, the OT will be remembered as cinematic classics, not unlike The Wizard of Oz. Or how the great animated features of Walt Disney, such as Snow White and Fantasia, are remembered today. The PT will slide into obscurity, remembered only by a select few.
I'll give an example. Everybody knows of Mark Twain's masterpieces The Adventures of Tom Sawyer, and The Adventures of Huckleberry Finn. How many people know of Tom Sawyer Abroad, or Tom Sawyer Detective? Both where written late in Twain's career, and both failed to live up to the originals. (On a personal note, i believe them to still be better than the craptastic quality of the PT.)
