Reminds me of a Raylon Givens line. "If you run into an as*h*le in the morning, you just ran into an as*h*le. If you run into as*h*les all day long, it probably means you are the as*h*le".
In other words if a ton of people complain about the dialogue in your last three big movies, you have a dialogue problem. Change what you are doing.
In the Freeport scene, where cheesy music drowns out the sales pitch of the Freeport agent it is obvious. The character doesn't care and it doesn't matter what the sales pitch is. He is there to case the joint for its various security pieces. Much of the film is badly mixed however.
I turned it up a little beyond reference level, and it made the crashing bits very loud and realistic while helping with the dialogue. My gear fortunately is up to that, but it is an assault on your ears for a long movie by the time you get to the end.
I've had the experience of recording music some of my friends do. I of course did it without compression. I could play it on my or anyone's really good system, turn it up loud enough and it sounded rather realistic. But every other person including the musicians complained. "I can't hear most of it when I listened to it in the car". So I didn't hyper compress it and crush the life out of it, but a certain amount of compression eliminated the complaints and everyone could happily listen in the car, via their ear buds or what have you. Nolan needs to listen to the complaints and alter his technique accordingly.
Oh, and I still think it was a pretty poor movie.
