The novel received mixed reviews.
James Wood writing for The New Yorker criticized the work saying that "Ishiguro is always breaking his own rules, and fudging limited but conveniently lucid recollections."
Alex Preston writing for the Guardian was much more positive, writing: "Focusing on one single reading of its story of mists and monsters, swords and sorcery, reduces it to mere parable; it is much more than that. It is a profound examination of memory and guilt, of the way we recall past trauma en masse. It is also an extraordinarily atmospheric and compulsively readable tale, to be devoured in a single gulp. The Buried Giant is Game of Thrones with a conscience, The Sword in the Stone for the age of the trauma industry, a beautiful, heartbreaking book about the duty to remember and the urge to forget."
