So anything that 24fps can do, 48fps can do too.
And I don't buy the crazy idea that someone using 24fps during an entire movie would someone be the achievement of some visual art perfection.
This is wrong, wrong and wrong.
Also I have to laugh quite a bit at you describing a movie called "The hobbit" which shows dragon, trolls, elfes, magicians, etc. as "trying to reproduce reality".
