JB-that's a good post,you have certainly highlighted area's that would have added weight to the storyline and if deftly handled perhaps wouldn't have made the movies too overblown or indulgent.
Lucas I would agree hasn't developed his film-making during the new movies , I suspect he thought about the type of stuff you mention but decided to go down the centre line,rightly or wrongly.
It's a game of opinions I was entertained during Clones and I would watch it again,as is clear from my numerious posts,a saga in itself,that my expectations were not that high possibly because I do not see the first 3 or 2 movies as classics just highly enjoyable fun movies and now I must go before the Dark Side forces me into any more posts on this subject.........................
