I call shenanigans. THX 1138 was like every bullshit student film I had to sit through in college.
I'll give it that it is shot well, and the soundtrack/sound scape is outstanding.
American Graffiti is even worse. I've never been able to sit through the whole film in one sitting.
Star Wars? Go watch the behind the scene's disc that came out with the last box set. Lucas was so over his head that they had to bring in a team of editors to fix his mess. They show some of his original edit...1950 Buck Rogers bad.
He is not a good director. His is a great visionary, technologist and marketer tho. His single handed advancements for the industry rival anyone involved in film the past 100 years. From THX/skywalker sound, to forcing 75mm/Digital into the mainstream, and ILM. Huge contributions.
