“Green Book” won Best Picture at the Oscars on Sunday. The film is set in the 1960s and tells the story of a friendship between African American pianist Don Shirley and Italian American driver Tony Lip. Despite five nominations and three wins, many people were not pleased that “Green Book” took home the big prize. In the LA Times, Justin Chang called it “insultingly glib and a movie that cluelessly embodies the white-supremacist attitudes it’s ostensibly decrying.” Is the criticism deserved?
