Somewhat niche personal pet peeve: The little “special features may not be captioned/subtitled” on home media releases. Why do studios seem to operate under the assumption that only people with perfect hearing will be interested in the behind-the-scenes goodies (or that even people with perfect hearing will never be in a situation where they want to pop subtitles on for some reason)?
If I could make a comfortable living off of it (or if I was independently wealthy and could do what I want), I’d love to have a subtitling/captioning business making sure that all parts of a home media release, including all special features (featurettes, specials, trailers, commentaries…it’s particularly nice when commentary tracks are subtitled, so that it’s possible to watch a movie with the original audio but with the commentary subtitles, or vice versa) had subtitle/caption options.
