These days I no longer pretend English is English. Subtitles have been known to fill out my understanding of some dialogue.
But some people would rather not watch a show they have to read to understand. Best caption moment ever for me was the Hunt for Red October, where they faded the subtitles out and turned up the English translation early in the piece. Hilarious.
I'll turn the cc on when something is dubbed in English. The frequent differences in tranlation are pretty funny.
