New movies have terrible sound. They play the score over the dialog so you can't hear what the actors are saying. The score should ALWAYS be muted when the actors are speaking. Same goes for sound effects, the "Foleys" (footsteps, doors slamming, traffic noise etc).
Then the actors have to stop mumbling. Even when whispering in a lovers ear, the actors have to enunciate clearly and remember that they are speaking to the audience.
The old classic movies understood this and their soundtracks are clear as a bell, even when the movie is fifty years old or more. The new movies are just plain hard to hear.
