There are definitely bad sound mixes out there. I remember seeing Tenet in a high end Dolby Atmos Theater wising I had a remote that could select a "close caption" option the screen. One of the worst mixes of dialogue for any newer film I have (not) heard.
Fast forward, when I redid my speaker setup and added my new center channel. I put Tenet on and could actually understand the people talking. I called my dealer to say I was happy with my choices. I did not even have to adjust the center level outside my initial setup.
