An optician grapples with the Indonesian mass killings of 1965-1966, during which his older brother was exterminated.

The Look of Silence delivers a less shocking -- yet just as terribly compelling -- companion piece to Joshua Oppenheimer's The Act of Killing.

'The Look of Silence' is a profoundly thought-provoking and emotionally devastating documentary that demands full attention. The film's dark, disturbing exploration of Indonesia's 1960s genocide resonates long after viewing, prompting deep reflection on human nature, moral responsibility, and unpunished atrocities. While intensely challenging and not for the faint of heart, reviewers emphasize its importance as essential viewing that offers powerful social commentary and crucial historical documentation of overlooked crimes against humanity.
