It is the movie telling only about the struggles of retired parents with their children but not the struggles facing by children with their retired parents.
It is the movie which giving half message to public who watch.
There are sons and daughter in laws who are still taking the responsibility of their retired parents and respecting them. The only thing in this movie is lack of patience of retired parents. Just giving up their lives doesn't mean the solution but it just fills the regression feeling in the hearts of their children's whole life.
