We all know the modern complaint: movie sound sucks now unless you have a high-end sound system. Frantically turning down the volume after turning it up to hear the dialogue only to need to turn it up again can be frustrating. Now, this doesn’t solve the underlying problem, but why not have a “Volume A” and “Volume B” you can easily set and toggle between with the simple press of a button?
I’d recommend them, if you enjoy that experience/process.
I did like that Tenet has layers. You can watch it as an action movie, no problem, but you can also go as far down into the story as you want to also.
