"I have the higher ground"? WTF?

Saw Revenge of the Sith tonight. Perfectly adequate space opera action movie, as long as nobody on screen talked. Very pretty special effects. As someone said, quite busy backgrounds, but that was definitely a feature since it gave something to look at during the embarrassingly bad attempts at romance and/or drama. Christensen and Portman probably did whatever they could, but with dialogue like that they were pretty much doomed from the start.
