This is so far the best movie of the year. It doesn't fail to capture your attention from the beginning till the end. I hated the interval because I was so involved in the movie that I really didn't want it to stop. The suspense that every scene creates will leave you thinking about what's coming up next. Neither the murder is concealed nor the murderer or the witness. Yet it's the power of this unpredictable story that intrigues its viewers. The actors have done a superb job. But, I also believe, the script writer deserves a huge hats off. Finally, the face of Indian cinema is altering.. Must watch it.
