Yeah, Lucas surrounded himself with sycophants and brown nosers, and no one was interested in rocking the apple cart. Lucas was best at big visuals, ie, Star Destroyer entrance, spaceship chases, etc. He was not good at dialogue, writing, etc. He also would make one or two runs at a scene, and decide that it was 'good enough'. Sadly, the Red Letter Media dismemberment review of The Phantom Menace pointed out a number of bits from behind the scenes shooting, where Lucas questioned whether what they were doing was good. He had some inkling of the failure of vision. But all the hangers on were telling him it was great.
Once the original trilogy was done, Lucas really hasn't produce anything of note.
