Films and TV shows and more often have subtitles, which are helpful for enjoying muted video, translation, people with hearing impairment, people struggling to understand accents, checking fast unclear dialogue and other reasons. They are important, and sometimes it's clear when they do something right or wrong.
Maybe we can't expect them all to be works of art, but there are certainly some easy wins even in the industrial media environment. What do you think?
What I like with UK subtitles, is that different characters get different colours. With translation subtitles this never seems to happen.
