I saw Laura Poitras’ immaculate doc right before it won Venice, it’s now being released in both New York and L.A. theaters. Tackling the American opioid epidemic via the eyes of photographer Nan Goldin’s battle against the notorious big-pharma Sackler family. This is a rich, sprawling and calculated study that plays almost like a great American novel. Poitras effortlessly meshes both of her storylines, Goldin’s life and her battle against Sackler, as an indelibly realized portrait of grief, corruption and personal freedom. You would think a doc tackling, and uncovering, big Pharma corruption would be the most interesting aspect of it, but Goldin’s life-story, told through her brilliant photographs, is just as fascinating, if not more so.
