From what I’ve read about them, George Lucas’s original plan for eps. 7-9 of the Star Wars series would have been more like eps. 1-3. An ancient order of the Whills as a force behind the Force would be explored, likely through a thrilling sequence of talking, chin stroking, talking, and sitting.
Slashfilm has a little of what Lucas liked about plans and artwork for episode 7, but the movie didn’t develop in that direction. According to Disney CEO Bob Iger in his newly released memoir, Lucas didn’t like that direction.
When Disney bought the franchise and Lucas’s outlines for the new episodes, they stated their freedom to develop them as they wished. “George knew we weren’t contractually bound to anything,” Iger wrote, “but he thought that our buying the story treatments was a tacit promise that we’d follow them, and he was disappointed that his story was being discarded.”
Lucas wanted something new with each movie, but Iger and his team wanted something Star Wars, “to not stray too far from what people loved and expected.” He doesn’t directly disagree with Lucas, but I’m glad the sequel films are not more like the prequels.
I remember enjoying The Force Awakens; I reviewed like this.
That pretty much sums it up without the slightest hint of a spoiler.
