Lucas is a great ideas man, but, he's horrible with details.
Didn't he write the awful dialogue and direct the awful performances in The Prequel Trilogy? And many of those actors that were directed so poorly in the SW Prequels are very good actors, so, the blame for their performance points pretty directly at how they were directed to perform.
