Anyone seen previews for the new HBO series that starts this Sunday night?

Any thoughts on it? The previews I saw made it seem pretty intriguing to me, I'm a bit of a historical fiction junkie. However, I've only read one review on it, and it didn't get too much good said about it.

I set my TiVo already so I can at least form an opinion of my own, I'm hoping the critic and I disagree.
Anyone else have any interest in it, or even know what I'm talking about?
