I know they say 'For Hard of Hearing' unless its a foreign language film. But I wonder how many people always use them. I mean a lot of content important to the film can be lost if you cant understand the accent. I watched a DVD without subtitles and even though I reversed over the dialogue 5 times I couldnt make it out and it could have been important or it could be misunderstood! This is espacially true if you are English but the film has a strong American or Cockney accent for example. Lots of movies have subs now but still too many do not.
