In spite of the rather good idea for a plot, the dialog was awful and ate credibility. McGregor and Portman did they work as professionals do, but it was shame how little of their acting capacity was used. A little more effort to persons and more length to certain scenes would have done the trick. The scenario was jumping one place to an another having no rational thought. Special effects were great of course, but one can not compensate acting with them. The most beautiful role was done by "Emperor" Ian McDiarmid, and he truly belongs to royals ones. Anakin's role was so seriously performed that it was almost comical. Watching this was like watching the bad ones in Idols. The sense of empathized embarrassment made stomach hurt.
