They should have cinemas for millennials
How young people watch movies is different to how they are expected to watch a movie.
I'm talking about a theatre that would have the lights on 'mood lightning', have free wifi. Allow you to use your laptop or phone throughout. Maybe instead of seats it could be chairs and beanbags. You could have your own speaker with you to not miss out on dialogue by people talking near you.
Maybe when you enter the cinema you join a chat room and you can group message during the movie.
Cinema is dying and it is because the younger generations just can't sit in the dark for 3 hours without being on their phones. They're wired for it. They are simultaneously existing in both the physical and cyber worlds. They can't kill off their cyber version for 2-3 hours.
