Hi, Mike.
This is Xuanrui Li (Sherry). I feel this movie is little hard to understand due to its language use and accent, especially for the first half of the film. Though I am not quite familiar with American history, I still feel that there are some metaphors hidden in this film. I have tried my best to understand them:)
How does this story represent the South?
First, the overall tone of the film is a little dull. I can even feel the dirt. It tries to show the audience that the South is less developed with emphasizing on farm. Moreover, the accent also accurately captures the characteristic of the South. The most important part is racism. We all know that nowadays the South is still having racist problem, and this point is also shown in the film, such as the KKK and political views.
How does this story compare with the Odyssey and The Wizard of Oz?
I have not watched Odyssey before, so I can only touch on The Wizard of Oz. I feel that they are somehow similar. Both of them are about hero's journey. They both have their ultimate goal of this journey, and during the journey, characters in the films all changed. For details, there are several scenes in O Brother parallel to scenes in The Wizard of Oz. For example, the KKK scene and the march outside of the castle scene. Moreover, they both use colors to represent meaningful ideas. For example, the wizard of Oz wears all white in the movie, showing that it knows everything being helpful to Dorothy. In O Brother, the politician and and his followers are all wearing white as well, showing that maybe he can lead the South to a better future--he is not the one with racism ideas.
How do Everett, Pete, and Delmar change during the course of the story?
Generally, they all know the importance of friendship during the journey. After encountering with the "devil" for several times, they realize the importance of their life and friendship. In the end, they all regret committing crimes and are willing to become common people.
