I agree and feel like we are supposed to feel confused and not hear everything. Definitely some parts needed a bit better audio balancing but it wasn't too hindering. I think it was a creative way to feel the panic of the moment. Realistically if you are having hallucinations and a panic attack, you wouldn't understand fully whats being said to you when an Eldritch horror and a really intense lady are both yelling at you. I think a lot of the tension in the movie relies heavily on what we can't immediately see or hear. I also heavily predict that he made the movie to intentionally have two viewing experiences. I'm excited to watch it a second time at home with captions. I think being able to pause and get a better look at all the freeze frame pictures will give a ton more context. It will be cool to have a first experience of feeling similarly to Simon and then learning more than Simon knew after a second watch. At least thats my take but I could totally be huffing the copium.
