Anurag Kashyap's takes the audience through a musical journey and his own theme of grey characters, dark world, and drugs. This is one of the best Bollywood movies that has used music to enhance the screenplay rather than the usual style of a foot-tapping dance of 100+ artists at an unwanted place in the story. The plot gets monotonous at some point later, but still this one is a refreshingly new take of a classic novel.
