I know some with perfect sight who use it as they can listen to a film while buzzing around the house with a set of headphones on. Its only annoying if you don't want it for something. There is now a trend for all movies to be made including it and in some cases the action etc, is adapted to allow it to be fitted in. Its only really what used to happen in radio plays and often you don't really notice. Of cours back in the early days of TV, many series, such as No Hiding Place or even early saint episodes had enough dialogue in them to explain the action anyway, as many of the writers cut their teeth in radio drama. Now its the opposite, Most adverts never voice what they are selling or say call the on screen number now. Some adverts do come with audio description on some channels, I've seen it on Virgin, Some BT ones most stuff made by Proctor and Gamble, some Waitrose ones and some others. Brian
