Caveat: I spend a lot of hours under headphones, and I'm sure this affects how I perceive speakers-in-real-space mixing...oh, and my hearing certainly isn't what it was, at age 52... But, do you find muttered dialogue getting buried further into the overall mix than in decades past? I'm wondering if current mixing standards, and more attention being paid to the surrounds, isn't diminishing comprehensibility in the quieter passages. And I'm not talking the bloated blockbusters, as much as (what used to be) the "smaller movies". I'm becoming more aware of actors' mumbling and babbling important plot points, wheras these used to be practically "stage-whispered" to the boom-mic in years past. I guess this isn't as much an issue if you're watching a film on The Sundance Channel, over a surround-sound-in-a-box system, where the center speaker is at least bookshelf-sized, while the rears are often smaller than a Subway sandwich. But, if I'm halfway-back in the theater, shouldn't I be able to get all the plot points without asking Michael Caine to speak-up?
