Ron Wynn from AllMusic gave the album 4.5 out of 5 stars stating, When an act called Sisters Love were offered a cameo in the blaxploitation film The Mack, their manager suggested that Willie Hutch do the soundtrack. It came to be one of the great 1970s film scores, including a pair of classic funk tunes, "Brother's Gonna Work It Out" and the title cut.[1]
