What's the criteria for "development?" Hmmm...let's think about this.... "Development" could be...let me see...well, understanding a character and his/her motivations? For instance, maybe Lucas could have explained why Anakin has been thinking of a girl every day that he met ten years past and knew for approximately two weeks? Why is that? Or maybe show a side of Anakin that isn't whiny and obsessed? Or a side of Obi-Wan that isn't a stick-in-the-mud? Or a side of Padme, period? Or a scene with Dooku, Palpatine, or anyone that doesn't only serve to grind the plot incessantly forward?
