I saw it twice this weekend, and loved it. I was very pleased that the Pevensies' characters were expanded on. Although Peter and Susan seemed a bit controlling through the film, I appreciated the focus on them since PC is technically the last Narnia film they'll be appearing in. Lucy was very sweet even though she'd grown up quite a bit since LWW, and Edmund! Oh, Edmund... *giggle* He was great. He was very amusing and definitely had went through the most changes since LWW. Caspian was pretty good, I would have preferred someone a bit younger, but he was impressive nonetheless. I was also very pleased with Reepicheep, Miraz, Cornelius, etc. I loved all the CGI, the music, the landscape... everything. The only part that I was a little uneasy about was the part just before Jadis appeared, with the hag and the werewolf.
That was a little creepy... I could certainly handle it, but it was creepy. And the kiss... I thought it was fine, and I have no objection to it, and I was glad it wasn't really anything more than a quick goodbye thing.
Overall, the movie was spectacular. It really got me back into the Narnian spirit. I didn't want it to end.
