The original entry at this URL, published 17 March 2014, has been removed. Revised and expanded, it forms a chapter in the book The Rhapsodes: How 1940s Critics Changed American Film Culture, to be published by the University of Chicago Press in spring 2016.
I explain the development of the book in this entry. 
Thank you for your interest!
