Teen movie you must watch. the acting of amitabh bachchan and nawazuddin siddiqui is hats off. I watch the movie, the way amitabh shows the desperation to solve the case is beautiful. I thing no other actor is good for the casting of both. the chemistry of both is great. even you will not get up in the interval from the seat.
I recommend to watch it once and spend a very good time with the friends.
