Sex and the City
Hell, I do subscribe to NBO and I have never watched a single episode of that show. I have surfed by a couple of times and found nothing worth stopping for.
Now the Sopranos is another matter. I am hooked but they also available for rental or purchase if you don't mind waiting a few months. Band of Brothers is definitely worth watching.
I constantly threaten to drop those premium channels. They are all a waste of money for the limited number of stuff worth watching.
