Why did the author feel the need to throw in a spoiler for the end of The Conversation in the last paragraph of the article? That seems contradictory to the point of everything else she wrote and disrespectful to both the audience and the film.
The Conversation came out in 1974, 52 years ago. By any reasonable metric, the statute of limitations on spoilers has long ago elapsed. If we can't even mention that Rosebud is a sled without some sort of spoiler banner, I think we're letting our preciousness about spoilers get in the way of actually discussing film.
She put it at the end of the article. If her premise is correct, it will remain safely unread.
