I watched "Last Tango" on Saturday, Sept. 19, but I could hardly understand the dialog. I have been a fan of this show since it began but this is the first time I could not understand what they were saying a great deal of the time. I checked with a friend and she had the same problem. What's up? I will rate it 5 stars only because I have always loved the show, but something was wrong with the sound and might be a local problem.
