I've been finding that the captions are often significantly ahead of, or behind the speech. For someone like me, who can hear to an extent but not enough to make out all speech, it's incredibly distracting. I'm trying to read one thing while hearing but not really being able to understand something else altogether. It's crazy confusing. It also means that the captions are being displayed with the wrong character on the screen so you don't really know who is saying what.
I do enjoy that the law and order theme is captioned [funky mystery music]. If only all captions were that descriptive!
