My parents lived through the depression, and they would have found themselves right at home in the world of Man's Castle. Bill's roughness is entirely appropriate for the times, given that he must live by his wits in a difficult world. Trina's sweetness seems a bit unreal, given the cynicism of our times, but I believed in it because Loretta Young gives a very natural and moving performance. She was only 20 and acts like a much more experienced performer.
The romanticism of the movie is wonderful to see. Borzage--whose work I'd never seen before--believes in what he's doing and makes us believe in it too. Roosevelt is fresh in the White House and there is a spirit of hope and renewal in the country. I could criticize the editing for being a little too abrupt (cutting the film down to fit the B part of a double-bill), as an example the scene with Bill and Fay in her rooms, but that doesn't detract from my admiration.
