Big B is hopeful, things will change post 'Pink'

Q. Very few films have the power to change the way we think. "Pink" is one of them. Which of your other films would you include in this character of motivational/inspirational cinema? Each and every Indian film has one basic message, victory of good over evil, and poetic justice in three hours. For me, then to differentiate one from the other, would be a wasteful exercise.
