To A Son About His Father - Dear Zachary- A Letter

Anyone who believes they understand grief, injustice, or documentary ethics. But be warned: you will not be the same person after the credits roll.

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.) Dear Zachary- A Letter to a Son About His Father

The true genius, however, is the third act— For those who don’t know the story (and this review will avoid the final spoiler, though the film’s reputation precedes it), Kuenne buries a knife that he twists not once, but twice. The editing rhythm changes; the music drops out; the screen goes black. What follows is a raw, unbroken sequence of Kuenne himself weeping, his camera shaking as he interviews Andrew’s parents, Kate and David. The formal structure collapses into pure, unfiltered trauma. The Emotional Mechanism: No Catharsis, Only Wound Most true-crime documentaries offer a form of closure: an arrest, a conviction, a moral lesson. Dear Zachary denies you this. Instead, it forces you to experience the Bagbys’ rage in real time. Kuenne includes the actual voicemails from lawyers, the bureaucratic letters, the footage of Shirley Turner laughing. He even includes a montage of her singing folksongs—a bizarre, chilling choice that humanizes the monster just enough to make her actions more incomprehensible. Anyone who believes they understand grief, injustice, or

Then, the film’s architecture shifts. The second act introduces Shirley Turner, Andrew’s obsessive ex-girlfriend who murdered him. Kuenne presents the facts coldly: she fled to Canada while pregnant, claimed the baby was Andrew’s, and was granted bail despite being a clear flight risk and danger. The Canadian justice system’s leniency becomes the film’s secondary villain. The film ends not with a verdict but

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 ).

Survivors of child loss, intimate partner violence, or severe trauma. This film is a weapon, not a comfort.

Dear Zachary is a masterpiece of radical empathy and radical anger. It is a letter that was never received, turned into a scream that the whole world heard. Watch it once. Remember it forever.
