MotionFlow and any other special feature touted on a tv, are all artificial techniques. It's certainly not indicative of how a 'true' 60fps Hollywood movie would look, any more than an upscaled DVD is representative of high-definition.
There's a glaring difference between 24 and 60, but I see nothing in the latter that effectively destroys the foundations of the traditional movie. Art direction does not change, nor does cinematography (to a point), or acting and directing.
I'm just not seeing how this is bad thing at all, asides from it being different from what we're used too. The complaints have boiled down to: it looks like real-life and it's too crisp. I mean...honestly I can't help but laugh in confusion. I very much think this is a result of our eyes being trained for such a long time to 24. Honestly if we get full motion-pictures shot and screened at 60 frames, I think it's only inevitable that people will grow to like it's advantages.
