Simply marvelous! Most of us did not even know the efforts and hard work of Indian scientists and what they are capable of when nurtured with bare minimum red tape bureaucracy. The execution: from the invention, trials, and distribution to 1.4 billion people is amazing and unprecedented in Indian history. Hats off to all scientists, bureaucrats, and the Indian Government for making it happen and the makers of this film to bring the untold story to us.
