Count me in as another fan of the books and the series. I was worried that the series would not be able to do the books justice, but have been pleased with the casting as well as production. Over the years I have read up through Snow and Ashes and agree with Greytness that after the first three or so they started, for me, to become more formulaic. But still enjoyed as DG's writing is so vivid. The first three will always be my favorites. DG is such a talented writer and at her best has that magical ability to transport us all back in time.
Greywings, you may be able to find the first series on Netflix. I haven't looked but if you use Netflix it would definitely be worth checking out.
I need to catch up on the 2 most recent episodes and they are on my agenda for today!
PS. I also love the History Channel's Viking series.
