Same goes for English too, my partner has a processing disorder with speech and needs subtitles to help her, and Netflix subtitles are among the worst we've ever experienced. Not just minor mistakes but completely different sentences that change the entire meaning of the conversation/scene. It's become an ongoing joke for us in our day to day watching, but is also annoying enough that if she actually cares about the show/movie we end up torrenting it purely for the better subs available.

Sometimes I am thinking they are community translated like on Rakuten Viki
