C3-PO
I believe beyond whatever anyone states about Jar Jar Binks, that the true disappointment of Episode one was the change in what C3PO represented. In each of the previous movies and even in a number of books, he has been a central focus that carried the movies. Whilst this was to be a start of a new trilogy and was to explain his origin, I believe that the film may have benefited from skipping from the ship fly by to the federation to Tattoine where we see his 'birth' I may be considered wrong but he has in the previous movies been a perpetual juxtaposing element or crux to the development of the movie. It could be said to be R2D2 who indeed did appear in the movie as a main character, but I feel that they could have retained their position as crux to the development on the saga if C3PO had joined earlier. He is not simply a narrator, or extra character. In the first movie, if it hadn't been for him R2D2 would never have joined Luke and then he wouldn't have received the message etc. However I would equally like to believe that Obi-wan and Anakin to be the second key element pairing to the saga as they are in all of the films. I still believe however that the Droids should be considered to be of greater importanc given that they remain in all of the films and much of the expanded universe. Sorry for my rant
