To me, there is one big give-away to this lie of Original Intent. All of those things that we know are in the file of original intent (such as Anakin wanting his son to have his lightsaber when he was old enough and Leia remembering her mother) aren't really in the films at all.
Obi-wan stopping to pick up Anakin's saber had to be filmed in pick-up shots because Lucas forgot all about it and wrote it in at the last minute. And no attempt to make the scene even match the original trilogy, either.
