I care dis-proportionally about experiencing the story, so to me a second watch loses a lot of appeal.
And tbh, I feel like movies are very meta and you also get more from each movie if you watch more movies/read more books. Like Doctor Sleep for example, is an adaptation of a Doctor Sleep novel, but also a sequel to both the Shining novels and movies. You would get more of it if you read the two novels and watched the shining movie than if you just watched the movie or read one of the novel twice. I also enjoy watching different adaptations of something and pit them against each other, like Let the Right In (both the novel and the movie) and the American adaptation. I guess that's my version of what you get when you watch a movie twice.
