That is fine that feel explanation is needed, but I need to see that you have tried to unravel why that is the case. What films have you looked at which supports your claim? Any texts read which brought you to this conclusion?
If your claims can be supported by comparing to other works, are the works which contradict your claim? If so, why are they less valid?
Also, with regards your comments about a faster pace being required, how would this have affected the limitations of creating video to support the audio? Are there any examples of strong contrast in pace of visuals to audio and what is the effect?
