It's not only to do with the film-makers ability to craft, or dial-down the perceived detail overload in 48fps. It's just as much to do with the viewers expectations and experience. Can you imagine showing a recent 24fps blockbuster action movie to a 1920s silent film cinema go-oer? The special effects, quick cuts and loud soundtrack would have given them incredible sensory overload. They would have left the cinema totally overwhelmed. I'm not saying 48fps is a similar level of advance, but it's the same principle. Not only do film-makers need to learn the new craft, we also need to learn to watch it.
