A story of avenging (it's not about revenge) rapists and murderers portrayed in raw form. It's too the point with brilliant direction and cinematography. The actors have done an outstanding job in becoming the characters and making the viewers feel connected to their emotions.
Since the violence is raw, it is not recommended for people who prefer "commercial movie violence". If you are one of those people, avoid watching this movie and spare this masterpiece from your negative review citing "Too much violence for me" or "I could not watch it". There is a disclaimer in the beginning of the movie so read it and use your discretion.
This movie is also not for the people who don't take rape and/or casteism seriously. You won't feel the agony or connection to the emotions of the characters in the movie if you are one of those people. And you probably won't feel that it was justified either.
