@CainsSon: You're arguing for the importance of artist intentionality with the movie director as artist. Artist intentionality loses power when the work of art reaches its audience. Directors intend people to watch their movies in theaters. But people can watch movies on their phones, so they do that. Directors intend people to watch their films at normal speed. But people can change the speed, so they do that. Artist intentionality has no effect on any of that.
Look another way: Let's say it's 1979 and we went to the theater to watch Alien. And the viewing was fine until we got to the climax of the movie and the projector breaks. So Ripley is running through the ship, the alien is lurking around every corner, and somewhere in there, the screen fills with that reddish-brown melting film color before going white. And we're sitting there for 20 minutes while they get it going again. Or say the film has been in the theater for a while and the reels are all full of scratches. The picture quality is naff the whole way through. None of that is how Ridley Scott intended for us to watch the movie. But that happened a lot.
Then people watched on TV, watched VHS tapes, watched DVDs, and on 'til this summer when we can ideally watch the 4k version on a large 4K TV with surround sound in our living room (assuming we buy all that). Or on our phones.
