This is, simply a great film.
Set in the 1930s, it really successfully captures the feel of the rural American South at this time, and does a super job of capturing the feel of small towns, farms, and Southern politics. Clothing details are well done as well. Minor details, such as references to the Tennessee Valley Authority, or a farmer cultivating a field of tobacco with a mule drawn implement, nicely place the film in context. Even the title is a shout out to the era, recalling the name of a fictional book which a fictional movie director is getting set to film in 1941's Sullivan's Travels.
