I think Jake Loyd could have done better, Hayden Christenson was ok for AOTC but he was much better in ROTS. Natalie Portman didn't have a lot of scenes or lines on ROTS, I think they deleted some of her best scenes, they should have left a lot of those scenes in. I also would have changed the birth scene/death scene. I think Leia should have been born first, Padme should have gotten to hold her a minute, then just as Luke was born Padme dies. It would have better explained why Leia has the "beautiful but sad" memories of Padme and Luke has no memories of Padme at all. But I did like that they put Luke next to Padme when she told Obi-wan that there was still good in Anakin, It carried over well into ROTS. but that just my opinion
