How Do You Measure a Year?

For 17 years, filmmaker Jay Rosenblatt filmed his daughter Ella on her birthday in the same spot, asking her the same questions. In just 29 minutes, we watch her grow from a toddler to a young woman with all the beautiful and sometimes awkward stages in between. Each phase is captured fleetingly but makes an indelible mark. Her responses to her father’s questions are just a backdrop for a deeper story of parental love, acceptance, and ultimately, independence.
