An exceptional personal documentary, Deborah Hoffman’s Complaints of a Dutiful Daughter is a beautifully precise, acute, intelligent, practical, touching, and even (at times) comic record of how she copes with her discovery that her mother has Alzheimer’s disease. Using video and audio recordings of her interactions with her mother and some on-camera statements of her own, Hoffman charts in haunting detail precisely what memory loss entails, not only for her mother but for her as she adjusts to the situation. Full of wisdom and insight about its subject, this 44-minute essay film is far from depressing.
