Comments: All in all the movie is disappointing. It lacks the signature and the genius of KB Sir's movies which we are all accustomed to - situations and dialogues which gives people the goose pimples, the amazing camera angles, tight close ups, non-verbal communincations, centrality of women, of music, of questioning conventional wisdom, and more. There is none of that here. All we get to see is an average, run of the mill story - boy-meets-girl, boy-goes-after-girl, boy-and-girl go around singing songs, girl reveals in the end that she has leukemia, boy and girl get married, girl dies. Dialogues, acting, camera work - all average. So many loose ends in the story. So many songs randomly inserted. This would be OK for any other director but not for KB Sir. Considering the stellar cast and crew in this movie, one fails to understand how such an ordinary movie was produced.
