I dont want to get into the details regarding the story as the other member who has done a review has done a great job...summarized it very well and to the point. Nonetheless I could not help but throw in my two cents and recommend this to anyone who is for classics and for TRUE cinema (Pyasa, etc.).
A very well directed film...and Sharmila and Sanjeev Kumar...it is impossible to call one as overtaking the other in talent...both do an INCREDIBLE job and one forgets and has to remind the self that Sharmila really isnt Kajli---of the two characters she played---Chanda/Kajli--- Kajli is definitely the harder of the two characters to play and no one could have done it better. She has lived that character...one feels her every emotion.
For those who are tired of the Kal Ho Na Ho and K3Gs of today this will be a total refresher...and for a change make sure you sit ready to THINK and be touched to the core during the movie and for many days after. Gulzar...he is a saviour for movie watchers who yearn for intelligent cinema in this age of pathetic masala movies.
