"Ah, the sci-fi movie. Most of us know it now as being the genre which costs boatloads of money and features either long, ponderous scenes of religious-level rumination, or else showcases epic battles of good against evil on a galactic scale. We know it from Star Wars, Primer, Interstellar and 2001: A Space Odyssey, and we know its creators by names like Christopher Nolan and Stanley Kubrick.
But it wasn't always this way. At one time science fiction was largely relegated to the grindhouses, where it was derided as being silly, childish and not worthy of serious attention. Some modern movies retain this aesthetic, and are featured here."
