O’Hara has been likened to F. Scott Fitzgerald for interpreting the United States of the 1930’s through fiction as Fitzgerald had the United States of the 1920’s. He has been likened to Ernest Hemingway in the cleanness and spareness of his style. He has been likened to the great naturalistic writers because of his trapped, doomed characters. The implication of the several comparisons is that he reminds the reader of these writers but fails to reach their level of achievement. What can be said with certainty is that he was a master craftsman, a prolific creator of works which have demonstrably pleased the reading public for many years.
