Jeff Wells of Hollywood Elsewhere is not so enamored of The Hobbit as a film, but is happy about the high frame rate, saying its "added detail is at least something to sink into." He also notes what he believes will be the sweet spot of HFR: 30 fps. He writes, "Everyone will be cool with HFR at 30 frames per second (the frame rate used by Todd AO in the mid '50s), and it will work with any film of any mood, focus or attitude. If everyone is saying "no" to 48 fps, which I strongly disagree with, let's at least talk about 30 fps. It's a significantly better thing than 24 fps (smoother, more fluid, less pan blur), and yet it looks cinematic."
