Old movies feel much worse for me, voices barely audible but sfx blow my ears out. But I also have sound from headphones, maybe that just works better with the newer mixes.

I’m sorry but, the 80s were more than a couple of decades ago. 1986 was 40 years ago.

Also 20 years ago this was still an issue. Plasma screen TVs were becoming accessible to consumers and surround sound was taking off in the home video space. TV was mixed for surround cinematic but not everyone had a surround setup yet. They had to write laws that said the tv commercials couldn’t be louder than the main content of the channel (though these laws were largely unenforced).

Depending on how far back you go a lot of those movies were only recorded in stereo and sometimes even mono. So the mixing was pretty straight forward. Surround sound and pulling the bulk of voices to the center channel is a large part of this problem. Then you’re kind of at the mercy of your device as to how well it down mixes surround down to stereo. Some are pretty decent, and others are pretty terrible. Now things like DTS:X and Dolby Atmos that have 11+ channels I’d expect this issue is only worse(these still fallback to 5.1 surround if not supported).

I have a 13 speakers Atmos setup sitting in my living room and this isn’t even remotely an issue. That’s absolute overkill for people that aren’t very into home theater though. As it’s an expense for sure.

I will mention there is a rare movie (I own about 4 thousand titles) that I need to adjust the center channel volume but it’s like maybe 1:250 movies. So sometimes the mix does just suck. I don’t really watch streaming so that might be its own can of worms for audio.
