This might just be my problem, but I really hate subtitles. It takes me out of the movie and in dialog heavy movies completely pushes out the visuals.
I never understood those countries, like Spain, which make dubbing some sort of national pride. No, Spaniards: dubbing sucks, you just don't know any better ;)
But even with other foreign languages I enjoy watching with subtitles. For starters, you learn what other languages sound like. Plus, let's face it, most dubs are terrible quality. And finally, it's surprising but you start picking up the language! I've never studied Japanese but I started picking up words and inflections just from watching Japanese movies (and the same happens with Korean, Chinese, etc).
In cinemas however, movies typically have subtitles.
But I also wonder if there's something related to how people read that factors into this aversion to subtitles?
For me, subtitles are almost invisible and I spend zero-to-negligible effort "actively reading" them -- they just sort of get absorbed by my brain while I'm watching what's on screen. So it doesn't really negatively affect my enjoyment or engagement with the show/film at all.
I think maybe the folks that struggle with or dislike subtitles view the act of "reading" subtitles as a mental context switch that interferes with the parallel act of watching and listening.
Sometimes I do watch some TV shows with subtitles on (English dub & sub) if they have very inconsistent audio equalization i.e. during some scenes music is super loud and then they dip into really quiet dialog so I don't miss the beginning part.
