His point about the viewer not noticing the translation, if done well, and that it's easier if he cares about the story, highlight some of my main complaints about subtitles.
Denmark doesn't have a tradition for dubs, but with streaming it has become used more often, and subtitles don't always get the attention described in the article. Very frequently it's clear that the translator have a poor understanding of US culture, when translating subtitles to Danish. I suspect the reason could be price. When translating to English, it fine if it costs a bit more, the translation will be used by hundreds of million people. Danish, it will be used by at most 6 million people, assuming that the entire population watch the same movie. Realistically, at the most 1 million people will benefit from a translation.
I still see Danish subtitles that are clearly made by a Swede, who just happen to know enough Danish that you don't notice most of the time and as mentioned, subtitles translated by someone with limited knowledge of the culture of the country that created the movie.
