Why I loved this movie, it because of its execution and performances. It has a good ensemble of actors like Sanjeev Kumar, Ashok Kumar, Farida Jalal, Aruna Israni, Sulakshna Pandit and Asrani and they all just give apt performances.
It is in the genre of mystery. Though it is not very difficult to predict things, but the way the story goes forward is really engaging. You will remain hooked up, even if you have watched it before. While the whole settings create good tension , the end is very touching and emotional.
The movie brings us close to family values and so I feel it is very relevant even after more than 4 decades of its release.
The song "Apne Jeevan ki Uljhan Ko" is a class apart .....in the voices of both Kishore and Lata
A movie to be watched!!
