I think it would have been much more accepted if it had been done to an animated film. I watched Brave in 3D a few days ago, and thought that it could have benefited from the HFR in several scenes where there was too much blur, or not enough, in cases where the image stuttered too much.
Seeing The Hobbit in 24fps almost doesn't look right to me now. It looks more "normal", but it doesn't look like The Hobbit anymore.
I'm pretty sure this is the way it's going. It's just going to take some time to get there.
