The New York Times closes its review this way:
In short, what we have in this rendition of Dickens' sometimes misunderstood "Carol" is an accurate comprehension of the agony of a shabby soul. And this is presented not only in the tortured aspects of Mr. Sim but in the phantasmagoric creation of a somber and chilly atmosphere. These, set against the exhibition of conventional manifests of love and cheer, do right by the moral of Dickens and round a trenchant and inspiring Christmas show.
