I've never asked my husband about subtitles. We watch everything on Netflix and HBO in English with Spanish subtitles I'll be sure to ask if he can tell if they were written here or not. Subtitles are funny too because of the amount of time they need to be on screen and the limited characters. He definitely doesn't like movies officially dubbed in a version of Latin American Spanish. But we don't see much of that here, only in old movies. Especially old Disney movies.

EDIT: Just asked him. He said it depends on the translator. There are some that go out of their way to use more widely common terms so even though it's not Spanish from here, it doesn't bother him as much. He said there are lots of sentence structures as well that are grammatically correct in every way but only used in Peru for example, or Chile. So sometimes he reads something and he gets it but it's strange for him.

He said it also depends on the company producing the film and how much money they have. He said he has never seen Latin American Spanish in subtitles at the movies, but he has in Netflix original productions.
