So the only argument against it is, again, just like with 3D, is "OMG IT'S NEW I DON'T LIKE NEW!"
No, it sounds to me like the main argument is it makes the movie look cheap and like a live theater production on PBS.
I'm certainly curious to see 48fps, but it just seems completely wrong for a movie like The Hobbit, which is kinda supposed
to have that dreamlike, larger than life feel.
"it makes the movie look cheap" can be translated into "it makes the movie look different".
