I would use subtitles all the time if it didn't ruin dramatic and comedic timing. I often find myself wishing movies and video games had "proper nouns only" subtitles.
This would be an excellent idea! Oftentimes I'll watch something, then in the middle turn on the subtitles and learn that I was misunderstanding the name of someone/something.
Even if I hear it correctly the spelling may be different and can give better context and cultural flavor.
In movie theaters, they'd show English language films with Danish subtitles and, often, I'd miss a comic piece of dialog because the subtitles let the audience in on the joke before I could hear it spoken, and then the audience laughter would drown out any chance I had of hearing the joke.
It was a bit frustrating.
