My DD is hard of hearing, so when she was visiting we turned on the captions on the TV, turned them off when she left. Later I turned them back on and now I leave them on. They do get in the way occasionally, but they make it so much easier to "hear" what's on TV. I really don't think it's my hearing, but that the actors mumble half their lines. The problem with the captions is that I find myself reading, rather than watching the action, even though I can hear and understand what's said 95% of the time. One advantage is that the lyrics to songs are also displayed. I never could catch the lyrics before, and sometimes they are actually quite good.
I didn't care for the initial re-boot episode of Will & Grace. Too much politics and not very funny. And I don't understand why those people haven't aged! I hope the series improves.
