Honestly? Sound mixing in a lot of movies and some shows sucks ass nowadays. You have uber loud explosions and then relatively quiet speech.
Tenet was an amazing movie (many disagree, but it's a matter of opinion - I really enjoyed it), but I wouldn't have heard half the dialogue. Subtitles helped.
It's all supposed to be immersive - after all, explosions ARE loud. But I don't want my living room to explode. I want a lower range of volume.
Shit, watch an old action movie. The speech isn't as quiet compared to the explosions and gunfire as it is nowadays.
