1) I cannot think of another story where the connotation and narrative dramatically shifts. I think this is because there are not many stories that provide such an opportunity. The Harry Potter series is unique, and it contains many characteristics that other series do not have. The books follow Harry's childhood year by year, and they track his growth, both physically and mentally. As Harry grows up he begins to perceive things differently, and I think that may be why the narrative changes. Either Harry psychological growth has allowed him to understand more, or allows him to look at situations in a different way. Many other stories don't follow a child's development as closely, so the dramatic shift in connotation seems to be unique to this
