[Child of the 7th Age]

A three-hour movie has to simplify something to cram everything in and this is one of those things that gets ironed out a bit. Actually, I think Pippin is an especially appealing character because he is so young, still learning and growing. This contrast also comes over better in the book than the movie. In the movie, you have no sense that Frodo is considerably older than his companions, particularly Pippin. As such, you lose something of the contrast in age between the characters.
