This maamannan as a movie is good with all characters played very well, screen play is good and music as well.
I have a question to this director past two movies you have already shown the caste issues and showing this same issue in this movie, is this the way you learnt about cinema. Always saying about casteism seems not to be healthy. Nowadays people start accepting low and high grade.
So a person whomever belongs to the orgin of a caste can't change his or her inner behavior or thoughts which is in its blood, better try different script next time.
