As i understand it, he always had the ideas for the episodes before and after, just couldn't pull it off with the tech available at the time.
Whats a sell out without people to buy?
I would say with everything hes done for films, sound, music & video games, he deserves just a bit more then being called a sell out. Simply put.
Jar-jar pisses me off sure, but considering most of the "parents" who went to go see the new-er star wars had young children "do the math" it makes sense to add some form of "child hood entertainment" to help the young kids "get into it" And besides...he was kicked out for being CLUMSY, and in the end is a well respected character. "He too grew up"
-sighs-
If you think george messed anything up, just wait till you see what "your generation" if kids will do to the intellectual property. I cant wait to see the "star wars reboot" in 2025. (strong sarcasm) 
The real problem is with the way hollyweird is going. There will be a remake of Star Wars in 2025, and some of the original cast will have cameos in it.
