I think her performance is very weak in AOTC. The only time that she actually seems to show some human emotion is the meadow picnic. In nearly every other scene, she looks like she's just going through the motions and doesn't want to be there at all. So what if George Lucas isn't an "actor's director"? Good actors can still act despite that. Look at McGregor, Lee, McDiarmid, Morrison, etc. Although I don't like Hayden's acting, at least he tries and looks like he enjoys being in a Star Wars movie. Of course the OT has some bad acting, but I'd rather have corny, overdone acting (Carrie Fisher) than wooden, stiff acting (Natalie Portman).
