I understand what you mean, it's unbearable to watch movies with people who enjoy the medium in such a casual way, I understand that you want to check your phone every now and then or maybe you need to go to the bathroom, but try to pay attention.
On the other hand, sometimes I enjoy revisiting movies with certain people who I know will appreciate the experience, I like to see their reactions.
I think I will vet the people I choose to watch a film with a bit better in the future. 😁
