That interview is maddening. Of course people flinch more at bad sound versus bad imagery, they're completely different senses. Our hearing is deeper and more archaic, more directly connected to our emotional than language neural centers, and harder to shut off.
Imagine someone being perplexed at people's "conservatism" with regard to smell. Pump an even slightly unpleasant odor into the theater and people walk out in droves. The tolerance for these types of risky moves definitely varies by sense.
Eh, if you ask people what they want they'll say a faster horse.
I can understand his point that you can go wild with visual effects in movies so he wants to experiment with sound. I do think his experiments are not successful though but you can't always pick winners.
I just wish I could get the unedited movies for home and have black boxes to fix the resolution instead of getting an edited movie. I don't mind not being able to hear the words when I can read them plus it removes second screen temptations.
