The Tomorrow War was originally meant to be seen on the big screen and so if there’s a silver lining to that it’s perhaps that the audience wouldn’t also need to wear ear protection.
At least watching the movie on Amazon Prime Video instead, you can turn the volume down. or turn it up if that’s more your thing.
Considering just how constant the explosions are I can imagine some in a theater with a massive sound system could have potentially been overwhelmed unless they too brought something to protect their ears.
