None of those were shot on 48 FPS. They were shot at 24p, or 24 frames per second, the exact same thing as the projected speed of film.
48 FPS better approximates human eyesight. The rate of 24 frames per second for film was arbitrarily chosen. Early films were anywhere from 18-22 FPS, and many cameramen wanted it higher than 24 FPS (in fact, I think there might have been some early high-speed experiments), but to do so would be very expensive so they compromised for cost. The only reason we ended up with a standard as low as 24 FPS was because studios didn't want to pay more money for more film stock and lab fees. It has nothing to do with aesthetics; it's just what we're used to seeing in movies.
