Here's the deal. I run on a treadmill 4 days a week for an hour and I constantly need something to watch while doing so. It needs to be on Netflix Instant, however. Some shows that I have enjoyed in the past have been: The Sopranos, Spartacus, House, Grey's Anatomy, Weeds, and Dexter. I have also watched some anime and really enjoyed it. Any recommendations for a good series on Netflix Instant?
