Guido is such a positive and hopeful man that he brings laughter to his son and to other inmates in the concentration camp.
One Jewish group said that this movie does not disrespect the Holocaust, because “It’s a fable about human values, and how a concentration camp can destroy those values” (www.time.com/time/magazine/1998/int/980223/the_arts.cinema.its_a_be17.html). But Guido brings some humanity into such a place. He can bring light into such a darkness.
Jesus experienced his own concentration camp of troubles, but he found light in his own darkness as he looked towards God.
