I would have paid extra for subtitles when I saw Tenet at IMAX. The audio mix made it extremely difficult to follow.
it doesn't help that they also have masks on for most of the movie, or they're having to talk over the sound of loud speedboat, or the accents are foreign, either russian or indian
Reminds me my dad said when he first moved abroad before he learned the local language, everyone would read the subtitles and laugh at the joke and then he couldn't hear what they had just laughed at.
