The Akshaye Khanna/Dimple Kapadia story was fresh, as far as I can see. I do not remember a hero falling in love with an older woman in Bollywood. (The Assamese movie, Brishti, handled this issue way back in 1974; but that was an 'Art' movie.) If properly developed, it could have been a nice 90 minute movie, based on this segment alone.
However, it was ruined by the million-times recycled Amir Khan story, not to mention the non-story of Saif Ali Khan. There is absolutely nothing new about the Amir Khan segment; no, actually the Opera was new! That segment is absurd; in real life that does not happen. And if it does, it is as rare as the life-style led by our heroes, at least in real life of real people in real India.
