I have to agree that when you only include the movies you lose the ability to show the other aspects of the universe (philosophy, politics, everyday life, etc.) Adding the other elements of the expanded universe greatly changes the aspects of the viewpoint that we have. Even in the movies (episode V in the trilogy, and II and III of the prequels if you can get past the corny dialog) you can see the effects that war have on an individual's life and love. Actually, in some area, all do a little bit. In episode IV, Luke loses his family because of war, and it shows how violence causes more violence, as this is what causes him to fight. Also, it shows that inaction in the face of a challenge leads to loss of your own (read the Greek/Roman mythology about Dapne). In V we see that Han and Leia have come together in love to be almost split because of crime and then separated because of war. In six, we see the power one person can have over destiny, and we see how a father's love for his son can overcome the greatest evil. (Vader comes from German for father). In ep. I, we see Anakin have to leave behind his mother and everything he has ever known in hopes of having a better life. In II, we see how the loss of family can be a drive as Anakin loses his mother to something he felt he could protect her from. In III, Anakin's overprotectiveness is what cost Padme her life, and in turn this loss of life is what caused the entire war in the Trilogy. All the violence, all the "Star Wars" are caused by loss and injustice, yet you say it isn't deep enough. Maybe it is just too deep to see.
