This is not a review of this film. It is an attempt to explain few things before you watch this film, so that anyone without a proper knowledge of what exactly the "story" wants to express to viewers will at least get an idea of what the film is all about.
This film is about a boy and a girl who falls in love - a boy is from one caste and a girl from another caste. Problem rises between them because the fusion of different castes is not allowed in India. What exactly caste is? It is nothing but fabricated way of dividing a population into a "caste". The fusion of different castes as I said is not allowed and it is the religion that supports this notion.
To the people who have no idea of how caste system works - be it people who live in India or live outside of India have to remember this only - It is this - Caste System works in two forms – In its preserving form, it makes intermarriage i.e. exogamy impossible and when caste switches to its religious form, it makes Untouchability prevailing in modern times.
Rest, the film will do the talking!
