The age old battle between heroes and villains will always be there, what fun would a world where there were no superhero movies and comics. Being a fan of such things is a part of growing up, it teaches you to be good and treat others with respect while it entertains you. In hero movies the super villain always has a reason for becoming the way that he or she or it is, but at the end of the comic, movie or series you learn that even if that evil doer is evil by nature or because something made them that way it is not right to hurt others and you must try to change otherwise the hero will give you a pounding.
yes, there are good lessons to be learnt from hero movies/series/comics but I always found it a Little funny and unfair...
