In Echo, I introduced the concept of the Visionary Ship - colony ships that carried hundreds of thousands of people in suspended animation across the galaxy to found a new civilisation. The Ships were the Bradbury, the Wells, the Heinlein and the Asimov. All named after authors who could, arguably, be called visionaries. Book two revolves around the search for the lost Visionary ship, the Clarke.
There wasn't a ship named after George Lucas. Although he was the saviour of science fiction, there are not many people who would think of him as a visionary. However, there appears to be a fine line between making stuff up in a subject that you clearly know nothing about - the Kessel run in 12 parsecs makes plenty of people shout "No!" - and being a visionary.
Something that's mentioned in passing in the films (although it's developed more in the written cannon), is moisture farming. On a planet with two suns, water is obviously going to be critical. Most rational people would dig boreholes, but no. Lucas decided it's extracted from the air. Yeah, right.
There's a place in Peru where it hardly rains and water is a real issue. They've built an advertising billboard and installed equipment that will condense water vapour from the air. It produces 96 litres of pure water a day.
Perhaps we could forgive the Kessel run. But we can never forgive the other crappy changes. Don't forget. Han shot first
