We all know the modern complaint: movie sound sucks now unless you have a high-end sound system. Frantically turning down the volume after turning it up to hear the dialogue only to need to turn it up again can be frustrating. Now, this doesn’t solve the underlying problem, but why not have a “Volume A” and “Volume B” you can easily set and toggle between with the simple press of a button?
Subtitles are great. I almost always have them on to aid comprehension. I find that I pick up on more subtleties that way. I feel like I still want to be able to process almost all of the dialog with audio alone so that the subtitles add an extra layer of understanding.
