Maybe I am overthinking it. Probably I do, as this is difficult to bring accross to children anyway. But keep in mind that there ARE quite a few morons (be they kids or grownups) out there who will unconsciously draw exactly the conclusions from the movie I named. I'm not being paranoid if I say that the influence of the medias, and medias of entertainment perhaps even more than news reports (which many a moron doesn't bother to watch anyway) can hardly be underestimated. They strongly influence our thinking in particular about thingse we've never seen in real life.
As for the revival of the badies I can just turn around the tables. Why would you think that there was such a revival when there was not a single winterly or ugly character to be seen after the battle? And as for the reality it would not have hurt if there had been just a single character whom the audience loves who died "beyond repair". A parting like the one of Littlefoot and his mother after her being killed by the sharptooth might have given a glimpse at the pain war causes.
Well, they did have the centar general, the fox, and Mr. Tumnus, although they were all repaired, it did make for a very clear point that anyone who got involved was in deep trouble if they were caught, and it was only by the miracle of Aslan that they were revived, which is what it would take to bring those ones back, so I can see how the hell of war is personified there.
I think for anyone to get the wrong message from this film: you'd seriously either have to have very incompetent parents, or you have serious observational, deductive, and logical problems, yourself. Any film can send the wrong message if it is taken the wrong way, but films, itself, cannot be blamed for people's actions.
As for no winterly or ugly creatures seen after battle, well...they really didn't show us much of what happened after the battle, actually. Just a ceremony and the kids, some years down the line, chasing a stag.
Just a character who just wants to be left alone and doesn't really care about whether it is summer or winter or if a Witch or a Lion is sitting on the throne. If a character doesn't care too much about cold weather and is not interested in politics that character won't be too interested in who is succeeding to a throne (preferably a throne far away) either. That would probably not be a character we would like (though he might be hospitable and friendly to anyone who doesn't mean to drag him along into a war that is not his own) neither would it be someone to dislike (not a supporter of the bad side either and clearly a peace-loving nature). It would be a grey-zone character.
A character like that would seriously have to have a large degree of indifference towards Narnia, his fellow Narnians, and how his country is run in order to be even be like that. How would this character have a peace-loving nature if he/she did nothing about it. Every day this character would hear about more and more Narnians dying, getting turned to stone, being tortured, etc. for doing nothing more than not accepting the witch as queen, when it's their right to do so, because she is clearly not the queen of Narnia. No, if you cared about Narnia at all, you sided either with Aslan, or with Jadis, because this was everyone's war. Just like WWII.
