How is reality treated in the aforementioned films?

I am comparing the W of Oz with The Chronicles of Narnia. In Oz they treat reality as the best thing there is. I mean, yes of course she does have a good time trying to get to the wizard but in the end there's always that famous line, "there's no place like home..." Where as in Narnia the kids neverrrr seem to want to come home. They find this whole new world and probably would be just fine living there forever. It's pretty much complete opposite for the two movies.
