10. ''Man in the Mirror'' (1988)
Jackson abandons his habitually slick video style — in fact, he barely even appears here — to reflect the song's message. Footage of revered cultural figures like Mother Teresa, Martin Luther King Jr., Desmond Tutu, and JFK is shown alongside devastating images of Chernobyl survivors, starving children in Africa, homeless breadlines, and civil rights protests. By far his least glossy outing, it is also by far one of his most affecting.
