I think 60 fps is great for video games and animation. However, I think 24/30 fps is much better suited for any type of "real life" filming. Whenever I watch a video on YouTube of any footage from a camera, it always looks off and unrealistic. I think it's something to do with the way our brain sees reality or something, lol, but 30 for camera recordings always look much better.
So, I think we should adopt 60 fps for animated movies, but keep it at 24/30 for films.
