Casteism in India is going since over the period of years and now also we do observe it in different part of Cities, villages, etc.
You can also see rural communities have long been arranged on the basis of castes - the upper and lower castes almost always lived in segregated colonies. How long such colonies would have a bifurcation on the bases of Caste?
Through this documentary it really shows the dark side of the society and its penetration in the mind sets of the people. Very good research, nice documentary. Must watch documentary.
