Its funny because all Peter Jackson did was trim the fat (no Bombadil) and gave Arwen something to do which meant the saga had four whole major females in it.
Also unintentionally, because Jackson was so detail oriented a person who is a not careful reader wlll realize just how racist LOTR is once they see how every fight is long haired white dudes (Good Guys) v dark skinned hordes in various levels of savagery (the Bad Guys).
