I just watched it! I love the added scenes and the coloring was so much better. Just the tiny, extra 30 seconds made it so much better and showed so much more of what each character was thinking. The coloring was also much better. Lucy's cheeks were actually pink with cold, and Edmund's bruise was that yellowish-green. I liked the extended battle scene, but the shorter one went better with the music. I also loved how when they got out of the river, they were paler, with cold, than they were in the normal version. Everything was so much more real, and the characters and Narnia were so much more realistic and brighter to me in the extended version.
And another thought, its on Edmund. When Ginnabrik attacked him, and he first sees the , he looks back, as if looking for a way out, but knowing he can't escape. That was added, and it showed a whole different side of Edmund, that he got himself into a mess, he couldn't get out of.
The extra blurbs added so much more to each characters personality and showed just how wonderful the actors are at getting across the feeling they want to get across. On the train when Lucy hands her toy to Edmund, she is trying to comfort him, but he hands it to the small boy across from him. Lucy looks hurt in a way...like she's about to cry, but when the little boy smiles at her in thanks for the comfort, she brightens just a little bit. And in that small instant it shows how caring and concerned Lucy really is for others. I got so much more out of the extended version. So much more feeling and vibrance.
