I wish that the Zahn books would be adapted Anchorhead i really do but Lucas does not understand good drama. He said in the empire 30th doc that nothing happens in that film and that they just stand around.
Kersh got star wars. He understood it was a fairy tale not science fiction. And he understood the human element. It does not surprise me that to this day Lucas still does not understand the impact of empire strikes back.
And since initially Jedi made more money Lucas thinks his instincts were right.
Make these movies cheaply and just good enough, they are like the old serials cop out became his manifesto.
