I totally agree. Replacing Shaw with Christensen makes no sense whatsoever. I don't mind the other changes with the shots of the other worlds (though I do miss the original Ewok song

), but that change plain makes no sense.
In fact, due to what was said in the third film, I don't get how Anakin appears at all, in terms of story. Originally, I think the idea was that it was a Jedi 'thing'; all Jedi become these ghosts when they die. But seeing as how Qui-Gon, Yoda and Obi-Wan are supposed to be the only Jedi that have figured out how to do it, how does Anakin know?
Anyway, I digress. How come you've not done a comparison of Leia in her slave outfit, eh?
