Flash Gordon, like SW or Dune, takes us out of the contemporary world in a way that most other successful SF films do not. Alien, Blade Runner, Minority Report, Matrix, etc are very clearly staffed by people just like us - but the neighborhood has gone to hell. SW stands as really the only successful trilogy that transports the viewer well away from real life. It is somewhat astounding that no one has really figured out how to get it right since, despite good attempts like Supernova, Valerian or maybe the Riddick films. But that period from 76 to 87 was pre-irony, so our ability to create something so earnest may be long gone.
