I think his answer is good!
BTW I can still hum the theme from Deadpool and the emotional strings theme from Fury Road so he managed to get some themes in there
IMO, just a general trend, older movies were more about capturing emotions inside the characters, and the edit was paced so that the movie would hardly work
without music. The Leone-Morricone movies and Spielberg-Williams movies for instance. Newer movies are more about capturing characters acting and reacting, and the edit aims to tell the story by itself. I'm not saying new movies are fast and old movies are slow. Just that there is less for the music to do. IMO Guy Ritchie is a great director at capturing emotions and character inside of an action scene.
