The reason to go to the theater is better picture and sound quality. As the article says film is already 4K with more color depth. Theaters need to go with 4K digital projectors, and 4k cameras for movie making, to show the quality they have now if they want to go digital. My home theater, and no one who doesn't have a home 35mm film theater, can't compete with the theater. To say one doesn't go to the theater because their home setup is just as good is delusional.
