This is a remarkable movie and the heart of the story is very beautiful. Two stories are intertwined. The first is simply the story of the persecution of the Jews by the Nazis during World War II. The second is the story of Oskar Schindler, a German businessman, determined to profit from the war by hiring Jews as cheap laborers. He is a womanizer, living the high life through in spite of the suffering around him. Steven Spielberg has artfully combined these themes by contrasting Schindler with the Nazi Commandant he interacts with and by the positive changes that develop in Schindler even as the evils of the Holocaust grow.
The movie is available (probably at your local library) on two video tapes. The first tape basically sets up the story of the Holocaust and how brutal it was. I understand that Spielberg thought this was important because he had become aware that many people today don't believe the Holocaust actually happened. There is a great deal of gore, nudity and other difficult content. Given the desensitization in our culture to gore and violence in movies in general, Spielberg may have felt that a graphic and realistic portrayal was necessary. I personally don't believe it is necessary to see all of this in order to grasp the importance of the story (particularly since most of my readers probably have no doubts about the reality of the Holocaust). I also don't think it's particularly healthy - spiritually or psychologically if you will - to plant such images in the imagination - particularly for young people. I suggest skipping this entire first tape.
The second tape focuses on the story of Oscar Schindler and how he rescued over a thousand Jews from certain death in the Nazi concentration camps. Even though it is milder in content than the first tape, it still contains some offensive/mature/objectionable content. Parents should definitely preview it before considering it for more mature high schoolers. Even then, it would probably be reasonable to edit certain portions with the fast-forward button. The ending is amazing and very powerful as we see the dramatic change in Schindler's character, his return to his wife and the Faith and, especially, his overpowering realization of the value of human life.
Despite the graphic scenes, the morals offered by the story in its entirety are good. I'm appreciative of Spielberg's acknowledgments within the story that Schindler's Catholic faith is connected with his good deeds.
