Cavemen - "Pilot"

The initial limited screening of the pilot episode was met with a less than favorable reception. The pilot was accused of being racist as some critics thought the Cavemen were being used as a metaphor for African-Americans and other minorities.[14] The series subsequently underwent a major creative "retooling", which included changing the show's venue from Atlanta, Georgia to San Diego, California.[15][16] The pilot episode has remained unaired on ABC.
