While the film does have its faults, it's still a faithful appraisal of the man about his life, his failures and achievements in ensuring peace, forgiveness and reconciliation for an entire nation. It shows that one human, despite his flaws, can make a difference to the world.
“During my lifetime I have dedicated myself to this struggle of the African people. I have fought against white domination, and I have fought against black domination. I have cherished the ideal of a democratic and free society in which all persons live together in harmony and with equal opportunities. It is an ideal which I hope to live for and to achieve. But if needs be, it is an ideal for which I am prepared to die.” - Mandela
“No one is born hating another person because of the color of his skin, or his background, or his religion. People must learn to hate, and if they can learn to hate, they can be taught to love, for love comes more naturally to the human heart than its opposite.” - Mandela
