The closed captions do seem pretty cheap. When they describe a sound, they always look like this...
<i>[ SFX: BIG CRASH ]</i>
I think the National Captioning Institute or the Caption Center/WGBH Educational Foundation would do better captions for the show. Some shows, like "Arthur," which is captioned by WGBH, features two caption options. "CC1" has regular captions, with everything (dialogue, SFX, etc.) in lowercase, and "CC2" has simplified captions, also all in lowercase, so when a dream sequence begins, it described the dream-sequence sound effects as <i>( Binky is dreaming )</i> and then <i>( Binky stops dreaming )</i>.
The National Captioning Institute mostly does all-caps captions, with sound effects described in UPPERCASE and in [BRACKETS]. It goes into lowercase when a character whispers.
The Caption Center/WGBH used to have dialogue in UPPERCASE, with sound effects in lowercase and (parentheses), plus dialogue coming from a radio, TV, phone, movie, etc. would be in lowercase. Nowadays the company does all captions in lowercase.
Personally, I think having the show captioned by one of the above companies (either the National Captioning Institute or the WGBH Educational Foundation) and use both "CC1" and "CC2" options. Isn't that a better idea?
Usually, until recently, Disney had Captions Inc. do the closed-captions for their videocassettes, DVDs and laserdiscs since 1988. (They used to have captions done by the National Captioning Institute or the Caption Center/WGBH Educational Foundation; these can be seen on mid-80s "Disney Classic" videos of their animated features.)
