Related to this topic, although I have no desire to question your experience or how you are doing your job, is the question "have you noticed movie audiences get smarter over the years in regards to the movie watching experience, specifically in regards to sound?"
The easiest visual example of movie audiences getting smarter is wanting better and better special effects. For those times humans are the VFX, the uncanny valley is a known problem - that still today VFX houses have problems overcoming.
With sound, like most technical people, I appreciate accuracy. One of my favorite movies for sound design/editing is "Speed" yet I know from watching various extras on that film there are quite a few liberties taken by the sound designer to give the audience participant a more visceral impact/feeling during some of the more intense action sequences. Disregarding Foley effects, since by their very nature are audio cues that are supposed to trick the mind.
I don't watch TV today, so I don't know, but does the squealing tires on pavement still happen quite a bit? I would expect Dukes of Hazard to have it since it was an old show, but surely audiences have advanced over the years? The Wilhelm scream, as you know, has become sort of an tongue-in-cheek joke when it is heard in a movie today. Again, I would hope that is a good example of audiences becoming smarter over the years. And for my biggest pet peeve, the sheathing/unsheathing sound of swords with leather scabbards. Watching the extras on LoTR, this was used because that is what most audiences expect, even if it is incorrect. That sound is still used almost without fail. The argument possibly being that these movies are fantasy and basis in reality has little use.
The core question stands, have TV/Movie audiences gotten smarter over the years such that some additional accuracy is warranted and appreciated? Or is the predominant audience still watching the Kardashians and don't care at all?
