Interracial Rorschach?

The movie “Green Book” has occasioned wildly divergent reviews, with some critics praising it as one of the best movies of 2018 and others saying it doesn’t deserve a single star because of its formulaic and demeaning trivialization of black experience.  The title refers to an African American travel guide which allowed blacks to travel through the Jim Crow South with a measure of dignity and safety. The movie is based on a true story about an unlikely interracial friendship that developed in 1962.  How can one movie elicit such differing reactions – and what do those differing reactions tell us about the state of racial relations in this country today?
