I also agree about the lack of emotion throughout the ROTS space battle. It was beautiful and stunning, but empty at the same time. To me, this pretty much sums up the entire PT. They are fun films, but lacking a lot to make a truly great series.
I would have preferred some other Jedi in other starfighters flying along with Anakin and Obi-Wan, cutting between all of them and having the others die off one by one (as in ANH) that would have added a lot more to the battle. Seeing the Jedi getting bested and losing more of the peacekeepers of the galaxy instead of expendable clones.
