'Kabhi Alvida Na Kehna' is a story about broken relationships. There are two couples - Shah Rukh Khan-Preity Zinta and Abhishek Bachchan-Rani Mukherjee. Both marriages are fast on the downward spiral. Abhishek yells at Rani, asking why his wife won't sleep with him. Rani snaps back that there's more to marriage than sharing a bed. Preity tells Shah Rukh that he's taking out his failed career frustrations on his marriage, and that's sad. SRK, eyes brimming with tears, turns and asks, 'you know what's sadder? Us.' The couples are estranged, and interlinked - their paths cross. And then there's Amitabh Bachchan, sharing some relationship wisdom as he wheezes from a hospital bed. Karan Johar got over 40 SMSs on the first day of the promos and everyone he speaks to is gung-ho about them.
