Srijit Mukherji never fails to amaze us . I love the way he directed this film in some unique way this time . Don't like to give spoilers afterall .And also i found the director to be in one of the major role in this film . It's the movie abt understanding the facts. Not just foolishly bring brainless conveying it to be national geographic channel . Combining everything it's the movie worth watching 2 times in movie theatre.
