The three I mentioned have clear character arcs in the saga, although Han's seems to take place only in ANH. I was thinking about it, and none of the other major players appear to have much of an arc. Leia doesn't really change throughout the OT. We see Obi-Wan go from Padawan to Master to hermit, but his personality doesn't really seem to be much different. I guess you could say he isn't that mature in Episode 1, but I dunno. Kinda iffy. And Padme is the same throughout the prequels, IMO. Am I completely off base here? Are there some major changes that Leia, Obi-Wan or Padme go through that I'm just missing? Are character arcs not that important to Star Wars? Is it more about the plot? How about the ST? Is it important to you for there to be clearly defined character changes in the sequels?
