I’ve only found two mentions of this HBO Signature series and one of them was by me? Is anyone else watching. I just started plowing through all the episodes on the HBO on Demand service? I’m up through Episode 10. Very compelling viewing. Anyone else watching?
I watched the first one (I think it was on your recommendation in another thread).
It’s intriguing and well done, but I decided there’s too much darkness and violence in what I watch and read. I’m taking a break, at least until dismembered bodies have an effect on me again. 
If you don’t like dismembered bodies, then you should skip the series. There will be many more. The body count is even beyond “Deadwood” levels.
I’ve only seen the first episode so far, and I have last night’s waiting for me on TiVo. I enjoyed the first one, and I’m eager to see what’s to come.
I made it through all the episodes. It will hold your attention. And it’s not exactly ideal viewing while watching the Yule log burn. But it’s good. I wonder if it would have been different if I had strung it out over 13 weeks. It might have been even more tense. I think the show’s time frame is about 3-4 months.
