Writing for The Spectator in 1936, Graham Greene characterized the film as "a rather dull film, [and as] a long packed melodrama". With the exception of the "sinister and satiric" first scene that was described as "brilliant", Greene took the view that on the whole "the film is too thick with drama". Taking issue with the film's genre, Greene suggests that satire and realism would have been more effective in handling the picture's themes.^[3]
