I’ve been a Prime Customer for years and yet still several movies do not have subtitles on Amazon Prime (not even English). It would be impossible to list them all here. It usually happens with movies from the 80’s and earlier - although even with some more recent ones. Still, Netflix manages to provide subtitles (and in multiple languages) also on old movies - which clearly shows a better service/ customer care as well as attention towards hearing impaired customers.Subtitles aren’t just for the hearing impaired—they help you to understand new languages, as well as decipher difficult-to-follow dialogue.
