LWLies’s review published on Letterboxd :
Self-taught, street photographer Vivian Maier was discovered in 2007 when Chicago historian John Maloof bid on a box of negatives at a neighbourhood auction sale. What he found began a five-year journey to uncovering the full, vast inventory of Maier’s amateur output. She possessed a prolific talent that should have been her meal ticket and, had she wanted it, earned her a place among the pantheon of 20th-century career-photographers. That it didn’t is the mystery John Maloof and behind-the-scenes co-director Charlie Siskel unpack with Finding Vivian Maier. Their film follows two recently published books: one of her photographs, one of self-portraits.
