Ozu Yasujirō was famous for his use of static cameras and lack of action scenes. His films are probably the most low-motion mainstream films ever made, which means they do not engage your brain very much in interpreting the 24fps motion. And yet they are still highly regarded by critics, and in my opinion highly engaging in terms of characters and story. Would they have been improved by shooting at 12fps, to make your brain work as hard as it does with conventionally shot films?

Also consider that a film is watched in a different environment and lighting than a TV.
