A Serious Man is a cinematic allegory of Jewish cultural detachment from nature. It is a masterpiece that elaborates on the abnormalities of the Jewish tribal existence.
A Serious Man does not explicitly touch upon issues related to Israel, Zionism, occupation, organ harvesting or anything distinctly identified with the Jewish state. It instead reflects on Jewish Diaspora life, Jewish segregation and the misery of operating within the kosher tribal template. It is about Jewish alienation both natural and human. Yet, A Serious Man also portrays a clear message regarding Israel and Zionism, for Israel is the Jewish state and, in spite of the Zionist promise to erect a civilized nation, Israel functions as a Jewish ghetto and is subject to all the symptoms of abnormality conveyed by the Coens.
