I'm the exact opposite - if a TV show/film doesn't have subtitles available then I won't even watch it. I don't enjoy going to the cinema for the same reason.
My understanding is that Cinemas often have what essentially are individual teleprompter reflection screens that you can use, and have CC projected onto them. It's an old feature, thanks to the Americans with Disabilities Act, and I don't know how well the feature or a replacement survived the digital transition, but legally speaking there is probably an equivalent.
So how do you watch international/foreign movies?
I guess they watch them dubbed?
I find that even worse than cc.
sure but the question was about how they handled things, not what was the true and correct way to handle things.
If the acting is any good, you can pick up a surprising amount of the plot without understanding any of the dialogue.
