A Princess of Mars

In this world, there are many different faces.  There are pretty girls, funk boys, sulky ladies, and handsome men.  However, in the world of novels, almost all heroes have clear-cut features.  For example, there are many handsome heroes in Disney movies; "Aladdin"; "Pirates of the Caribbean"; "Peter Pan," "The Lion King," "High School Musical" and so on.  Captain Carter, who is the main character of "A Princess of Mars" by Edgar Rice Burroughs, is also good-looking.  Why do they have nice-looking faces?  Well, the reason is easy to imagine. That is, people like handsome heroes better than bad-looking heroes.  I suppose that everyone likes handsome main characters.  If main characters are handsome, we can enjoy imagining them.  It is sure that there are many main characters who are nice-looking.  However, is there no main character who is bad-looking?  The answer is NO.  The main characters of "Harry Potter," "Spider man," "Spirited Away" are not good-looking.  Then, why do they have ordinary faces?  I think we tend to empathize with main characters who are similar to us.  In addition, when main characters are not perfect, we feel like giving aid to them.  This is one of the most important thing for novels; we can feel main characters are very similar to us, and enjoy growing up with them.
