For me it’s a bit of a distraction. A worthy distraction, but a distraction.
Live captions follow live speech by five seconds or more. It removes the dialog from the action. You watch the touchdown and the replay before you read about it.
When it’s live, words are misspelled or a similarly sounding word is substituted for the correct on. Watching captions isn’t like listening. Context is missing.
The Tender Trap is on TCM at the moment. TCMs captions are great. Nicely formatted. In sync with the on-screen dialog. Out of the way at the very bottom of the screen.
When captions are on it’s hard not to look at them instead of the film. I find myself having to consciously move my eyes back to the actors.
All this is small peanuts. For my dad, for whom hearing is difficult, captions work.
