"[A] mature, masterfully acted human drama."
— Peter Debruge, Variety
"Pieces of a Woman is a delicate, devastating account of an all-too-common but little-spoken-about sort of grief..."
— Hannah Woodhead, Little White Lies
"Pieces of a Woman is grounded and intensely personal. Much of that is due to the towering and heartbreaking performance by Kirby."
— Steve Pond, TheWrap
"Vanessa Kirby clearly deserves an Oscar nomination for Best Actress. She is that good, the role is that great and now she is the leader of the pack."
— Dwight Brown, National Newspaper Publishers Association
"Wéber’s writing and Kirby’s performance, working in concert with Mundruczó’s dazzling, multifaceted direction, Howard Shore‘s gorgeously mood-appropriate score and, again, Loeb’s drifting, searching, soulful camera together create, from so many disparate pieces, an entirely complete portrait, that even suggests further internal universes still to be explored, universes every one of us contains."
