I'd argue that if you only watch a recorded program once you haven't really seen it.

It's impossible to catch everything in a well made film on first viewing. Not everything is worth watching more than once but for me the first rewatch of a good movie or show is actually much better than the first viewing.

I like knowing what is going to happen, and having the freedom to let my attention wander to aspects of the media besides the primary plot and dialog, and keeping up with what is happening.

Not everything is worth watching twenty times but anything good is at least worth two viewings. The very best media has layers that unfold each time you experience it.

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.
