Indian cinema has undergone transition recently. Recognition of character actors, experimenting directors and writers has brought a long awaited pleasant change. The movie is a great representation of all that.
Positives:
Solid casting, no big names yet powerful and suitable actors chosen. Nawazuddin, Radhika, Tigmanshu and many more are all one of the finest actors in India and they definitely deliver a punch.
Story although a bit Poirotesque but still beautifully written. The slow build culminating into a big finale is crafted with precision. May be inspired by Agatha Christie's style where everyone is a suspect, but still the suspense is created and kept me guessing till the very end. The curtain raiser we had, I never saw it coming. The love story woven into a murder mystery may sound Bollywoodish but that doesn't derail the plot.
Negatives:
The songs had no place in the movie and seemed a bit out of place. They tried to do Gangs of Wasseypur here by even going with off beat and classical lyrics, but things did not click.
Conclusion:
Good thriller and a right step into right direction by Indian cinema. Time to recognise good actors and movie-plots rather than going for spicy formula and celebrity actors.
