Seeing a movie once, and only once, forever
Before the mass adoption of video home systems (VHS) in the early 1980s, the only place you’d see a movie was in the theatre, and the only time you’d see it was at the time of its release. Sure, you could go back to the theatre during the two weeks it was playing, and see it again and again. If the movie was unusually popular, it might be held over for as long as a month. Eventually the screening would end, and the movie would disappear into a black hole with no plan or expectation of a re-release. There was no option of renting or streaming. And since sequels (and prequels) have become commonplace only in the last couple of decades, chances are there would be no revisiting of the story, ever. You’d move on to the next movie, and your recollections would be the only thing you’d have.
