This movie is inspired by the life of the late south Indian actress Silk Smitha. The first half of the movie is fast paced and interesting. Very captivating to see how a conventional looking girl-next-doors, defying all conventions, becomes a sex siren. The movie starts to drag in the second half. It could have been made lot crisper by reducing run time by 30 minutes with some good editing. Vidya Balan is superb in her role. Emraan Hasmi, Naseeruddin Shah and Tusshar Kapoor does justice to the roles assigned to them. The biggest attraction of the movie, in my opinion, is not Vidya Balan's seductive movies but powerful dialogues! Every dialogue of the movie is worth quoting! I would have enjoyed it equally if i had just listened to the dialogues!
