Watching a movie on Vision Pro is like watching a movie with AirPods. Sure, it's immersive, but people love to watch movies and shows in couple or with friends.
I like my AirPods Pro with spatial surround, but when I watch movies with my girlfriend or with friends, we surely won't watch the movie wearing our AirPods while seating next to each other. We will watch it in stereo or even mono and be able to share the experience together and talk to each other.
Since media consumption is often a social thing, I think all this 3D or VR content won't be as popular. Of course, this is just my 2¢.
I mean, I can't imagine a group of people watching a sports game all wearing a VR set and AirPods.
