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.
It has nothing to do with movies, but I was posting my reply here and the page updated realtime itself like three times while you were editing your post. I saw your edits almost instantly. I found that feature neat, compared to reddit. Also, agree on the loud noises.
Ah, I watched it in the cinema and while mine wasn't the worst, in some cinemas it reportedly was completely unhearable.
Of course with piracy in particular there's another thing - people will often download a 5.1 or 7.1 audio track movie because that's the first available torrent they find, but then play it on stereo speakers on their TV or computer and the discrepancies in volumes will be huge.
