That said, I find 24fps significantly jarring for action sequences, particularly in 3D. 48 fps is certainly welcome. The Hobbit has a unique dilemma, however, considering it is high fantasy and extensive make-believe. 48 fps is more realistic, unquestionably so, and I understand how that can break the suspension of disbelief in such a film, for many of us who are irreversibly conditioned to the look of 24 fps.
I would love to hear how the generation that grows up watching 48 fps movies will feel about 24 fps.
