No, it wasn't. It was a "portrait" of a white Democrat city councilman (excuse me: "councilperson") who runs all around the place insisting he's "sensitive" and a detective (who happens to be black) who is persuaded that he should suppress evidence that would exonerate a white cop facing prison because he is thought of as being "racist" (the message clearly delivered in the movie being that because he is "racist," he probably deserves to be in prison for that alone), among other similar plot lines.
Didn't watch the Oscars, but I'm not surprised to read that this piece of politically correct agitprop took the top honors...
Crash doesn't even rise to the level of 'agitprop'. It is tepid, predictable, and safe.
Perfect Oscar material.
