What I don´t accept is some people say in his defense, "he was always like that and now people hate his movies". If you look back at A New Hope, which he directed, you can tell the difference. No, he never wrote David Mamet dialogue, but Luke, Han and Leia sounded reasonably close to actual people, not everybody in the franchise sounded like Shakespeare´s dumb cousin. Second, they were charismatic, likable characters, Han and Leia´s love/hate banter was pretty entertaining, now pretty much everybody is equally cardboard and pompous. I still liked ROTS, though.
