What i find hilarious is that episode VII originally would have opened around the 10th anniversary of Revenge of the Sith.
But was moved to Dec which had nothing to do with crapping all over the prequels or the may release but more to do with the second avengers movie.
Rinzler was writing a making of book for episode I that Disney cancelled, and since Lucas is not involved with episode VII i doubt he will be writing a making of book on that either. I hope Disney hires Rinzler to write that book but i doubt it will happen.
The original plans for the prequels/sequels is an area i find interesting but will remain a mystery. We only know what little Rinzler revealed in the making of return of the jedi. From Lucasfilm officially and from firsthand production materials and sources.
As for Episode I it was like watching a children's film made by the Walt Disney company. Along with the character Jar Jar, a character obviously borrowing elements from both Goofy and Donald Duck.
