However, Kuenne’s defense is embedded in the film’s purpose. This was never meant for a public audience. It was a private letter to a dead child. The fact that it became a global sensation is secondary. Moreover, the Bagbys have publicly endorsed the film, using it to advocate for legal reform. The movie became their weapon. When Kate Bagby looks into the camera and says, “I want her to rot in hell,” you don’t feel manipulated—you feel like a witness. Kuenne is a composer, and the film’s piano-driven score is deceptively simple. Early on, it’s warm, nostalgic, almost saccharine. After the tragedy, the same melodies return, but they are fractured, played in minor keys, or suddenly silenced. The sound design mirrors psychological fragmentation: home video laughter is abruptly cut by a news anchor’s monotone. The editing becomes more jagged as the film progresses, as if Kuenne’s own composure is disintegrating.
The use of repetition is devastating. We see Andrew’s face dozens of times—smiling, joking, being silly. By the end, each recurrence feels like a fresh stab. Kuenne understands that grief is not linear; it’s a loop. Dear Zachary is often cited as “the saddest film you will ever see” and “the film you can only watch once.” But its legacy is more than emotional devastation. It became a grassroots tool for bail reform advocacy. It also permanently altered the documentary form, inspiring a wave of intensely personal, first-person true-crime films (e.g., Three Identical Strangers , The Act of Killing ). Dear Zachary- A Letter to a Son About His Father
Survivors of child loss, intimate partner violence, or severe trauma. This film is a weapon, not a comfort. However, Kuenne’s defense is embedded in the film’s
Dear Zachary is not merely a documentary; it is a cinematic howl of grief, a homemade weapon of outrage, and a love letter soaked in tragedy. What begins as a sentimental biographical scrapbook for an unborn child quickly morphs into a true-crime nightmare and then, devastatingly, into a searing indictment of legal and social systems. To review it deeply is to navigate a minefield of emotion, because Kuenne’s film achieves something rare: it weaponizes the viewer’s empathy against them, leaving you shattered, furious, and fundamentally changed. The Structural Genius: The Bait-and-Switch of Genre Kuenne, a composer and filmmaker, starts the film as a memorial for his murdered best friend, Dr. Andrew Bagby. Using home videos, interviews, and his own warm narration, he paints a portrait of Andrew as a brilliant, joyful, beloved doctor. The aesthetic is intimate—grainy footage, heartfelt piano scores, talking heads wiping away tears. The intended audience is Zachary, Andrew’s unborn son. The fact that it became a global sensation is secondary
Anyone who believes they understand grief, injustice, or documentary ethics. But be warned: you will not be the same person after the credits roll.
The film’s central question is not “Who killed Andrew Bagby?” but “Why does a system protect a killer over victims?” Kuenne’s rage is laser-focused on Canada’s bail laws, but he’s wise enough to show that anger alone is simplistic. The deeper wound is existential: How do you go on living when the world refuses to deliver justice? Dear Zachary raises uncomfortable ethical questions. Is it right to show Andrew’s parents sobbing uncontrollably? To broadcast the details of a toddler’s death? Kuenne never asks permission from the audience; he forces intimacy. Some critics argue the film crosses into emotional pornography—using real suffering for dramatic effect.
Crucially, the film reframes the concept of “justice.” It argues that legal punishment is insufficient; what the Bagbys really want is the impossible: the return of their son and grandson. The film ends not with a verdict but with a dedication to Zachary—a child who never got to read the letter. That final title card is a gut-punch, but also a strange act of love. The film fails to save Zachary, but it ensures he will never be forgotten. Rating: ★★★★½ (4.5/5) – Half-star deducted only because the film’s relentless anguish can verge on numbing, and its anti-Canadian legal system polemic, while justified, lacks nuance. (Canadian viewers may wince at the broad-brush condemnation.)
