well, in story he was caught up in his own hubris and didn't notice Vaders turmoil while trying to KILL HIS SONin the real world Lucas didn't have the tech to make the Jedi/Sith as powerful as he would have liked, hence why Dooku, a 100 year old man was able to do flips off of balconies and beat up on two young, powerful Jedi but old Ben could barley parry a blow from a stiff cyborg.
He wasn't caught up by story. He was caught up in his own mind when he changed everything he once created. Then it didn't mesh well anymore.
Read the excellent Making Of... book that came out the past three years, and you'll see how much Lucas changed his mind about SW, even about the very essentials.
