Should have had JJ Abrams do all three of the movies and then let Rian make up his own, it really fudged it up by having ia new guy come in for the second movie and basically take a wrecking ball to some of the threadlines it left for the later movies and I don't think JJ expected him to do that kind of thing.
Sorry, wrong.
Abrams was very effusive and supportive about Rian's script, so much so that he admitted after reading it that he wished he was directing it.
The notion that Rian's script was some manner of deviation from Abram's vision is simply untrue.
