Robot Chicken Star Wars parodies are usually quite fantastic.
A lot of people worked on Star Wars detours and their work was never seen. So that just sucks for those people. I thought it was shelved due to Disney taking over. Lucas had every intention to release it once someone bought it I thought.
Calling Lucas a complete evil man is so extreme. If anyone who says that was in his shoes I doubt they would do any better. Most would do worse.
I think the success of Star Wars was a fluke. Many serendipitous things came together to make it what it is and it was hard for him to see what truly made it a success.
