Created by Paul Henning and set in the fictional town of Hooterville, it shared the same fictional universe as his other two shows, The Beverly Hillbilles and Petticoat Junction. While superficially the inverse of the former (Metropolitan family in Rural America vs. Rural family in Metropolitan America), all similarities ended there.
Green Acres was an exercise in absurdity, surrealism, culture jamming and Dada-ism. The bizarre community of Hooterville can best be described as Lake Wobegon on LSD. Townsfolk included:
The series would frequently break the fourth wall by having Lisa interact with the opening credits. Sometimes they would appear on her "hotscakes" as she was preparing breakfast. Other times she would react to them when they appeared in the dark at bedtime. Oliver was predisposed to long-winded speeches about "The American Farmer". When he would start to deliver one, patriotic fife music would often start to play in the background, and the townspeople would begin to search for the source.
Ironically it was Lisa, initially reluctant to come, who fit right in with the townspeople, while it was Oliver who was permanently befuddled and the only one in the community who was not in on the joke.
Despite consistenty high ratings, Green Acres was cancelled in 1971 along with its two sister shows. CBS, in its not so infinite wisdom, decided to cancel its "Rural" themed programming in an attempt to appeal to a more "sophisticated" audience.
All in all it was a show ahead of its time. Green Acres we are there!!
