Everybody knows that unusual ideas are always welcomed in cinema.This is an observation which holds for French director Robin Campillo's film "Les Revenants"/"They came back".This is a socially relevant French film about old people who are given a new lease of life.Although this film talks about dead people,it cannot be classified as a zombie film. France is an economically strong European nation which is thinking hard about its old people."Les Revenants" is a socially relevant film which goads us to reflect on the plight of old people.It is not only France which has to think about aging population.Many economically developed nations would soon have large population of old people.It is for them to device strategies to make life worthwhile for their old age denizens. This is why "Les Revenants" is more a film about French society and its handling of issues related to old people's welfare and well being.Film director Robin Campillo and his screenwriter Brigitte Tijou have written a gripping scenario which continually asks what is to be done with dead people who have come to live with living people.This exceptionally sound narrative gives rise to a series of poignant observations about old people and their behavioral traits with surprisingly uncommon results.PS :Film critic Lalit Rao would like to thank a good friend Mr.Philippe Pham for having gifted a DVD of this film for detailed analysis.
