A Separation (in Persian Jodái-e Náder az Simin, "The separation of Nader from Simin") is a 2011 Iranian drama written and directed by Asgar Farhadi. It focuses on an Iranian middle-class couple who separate, and the conflicts that arise when the husband hires a lower-class caretaker for his elderly father, who suffers from dementia.

"You cannot watch this film without feeling kinship with the characters and admitting their decency as well as their mistakes. The American films made this year that deal with the internal detail and difficulty of family life are airy, pretty and affluent compared with A Separation."
This should be enough to induce you to see this amazing film. You will carry Nader, Simin, and the other characters away with you.
