"Nolan sound-mixing bad" is a very confusing complaint to me
This is such a confusing complaint to me, it feels like a reddit inside joke at this point. Outside of Tenet (which was less "I couldn't hear the dialogue" for me and more "it's so fucking loud I'm going deaf") and Dark Knight Rises (which got completely fixed on release), I've never had a single problem with hearing the dialogue in his movies. But I see redditors, especially on r/movies, love to bring this up under any post about Nolan, EVER.
It's like their favorite joke as an easy karma hack to get free quick upvotes - just type "can't wait to not hear the dialogue haha"...
Maybe it's a specific theater you go to? Idk I've gone to digital IMAX and Dolby for most of his work - no complaints outside of the cases I mentioned. Not Oppenheimer, not Interstellar (I know a theater in the US that put a sign saying that the "loudness" of the movie was by design, but it has nothing to do with the dialogue), not anything else.
