Jaane Jann is actually an inspiration from a very famous book. I was not aware of this book so I watched the film as a completely new film with a brand new concept of it's own. The film absolutely rocks at the start with amazing acting produced by all the main actors , plot twists etc. But in the later half , the film becomes a little monotonous with unnecessary scenes dialogues etc. The ending of the movies could have been improvised with more detailed explanation and it seems that the the movie is finished in a rush. There also remains various unanswered questions in the viewers' mind. Moreover Jaane Jaan is definitely a good film worthwhile for watching it once but it is not as good as they claim it to be.
