I think they did resolve their differences in the end. Kind of. But since there wasn't a scene where they became friends or anything, it just seemed that they had to get along because there wasn't any choice. I might read the book version soon...ish just to see how much were changed/left out and to look for more Peter and Caspian subtext.

Clearly, Peter is the problem child this time around, isn't he? But just like with Edmund before, I really can't blame him. And he did pull through in the end. As for Caspian, well, for a titular character he didn't really get to do anything. :/ Other than save Susan that one time and... unintentionally stir up trouble. Almost resurrecting the Witch = Bad. D<

Yes, Peter and Susan will be missed. :( If it's any consolation, I think they'll be back in the last book? Assuming the third one isn't the last of these movies...
