The Orville is being described as a mix between Seth's show Family Guy and the beloved series Galaxy Quest. Some people are also considering it a Star Trek parody!
Officially, the show is "a one-hour science fiction series set 400 years in the future that follows the adventures of the U.S.S. Orville, a mid-level exploratory vessel. Its crew, both human and alien, faces the wonders and dangers of outer space, while also dealing with the familiar, often humorous problems of regular people in a workplace...even though some of those people are from other planets, and the workplace is a faster-than-light spaceship."
