>The performance style of actors in current TV shows and movies is more naturalistic and less elocutive than it once was, so characters are more likely to speak softly.

Yeah, I've given up on new movies. If I want naturalistic without a storyline, I can just go outside. I'm not going to turn the volume up to the level required to hear the mumbled whispers, just to have my hearing damaged by the next gunshot or blast of music.

Subtitles aren't a fix -- they're distracting and therefore annoying. A selectable "classic" audio track would be the fix.
