The Simpsons [SEP] Themes
"The Simpsons" uses the standard setup of a situational comedy, or sitcom, as its premise. The series centers on a family and their life in a typical American town, serving as a satirical parody of a middle class American lifestyle. However, because of its animated nature, "The Simpsons" scope is larger than that of a regular sitcom. The town of Springfield acts as a complete universe in which characters can explore the issues faced by modern society. By having Homer work in a nuclear power plant, the show can comment on the state of the environment. Through Bart and Lisa's days at Springfield Elementary School, the show's writers illustrate pressing or controversial issues in the field of education.
