I've just gone through a life changing experience. It's called Black. Mr Bachchan's performance is the best I've seen by a male actor. And Rani! My God! When I remember how I used to scream instructions at her during Kuch Kuch Hota Hai, I wonder what I was doing. Rani has not just surpassed her contemporaries but almost everything done by actresses in our cinema in the last fifty years.
