I just saw the movie yesterday. This movie is based on the story of a Mothers revenge for her daughter. Devki and her family were living a very happy life. Then Devkis step daughter Arya was raped by some people and after that they were not found guilty. So, Devki took revenge in her own way to punish them.
Performance of Sridevi as a mother was superb. She has played the role of a mother very strongly. Dialogue delivery was excellent. Nawazuddin and Akshay Khanna are in supportive role.
Music is given by A R Rahman. After all it is a must watch movie.
