I'm surprised more people aren't talking about this series (though we can rest assured more will once it starts airing).
As Heretic said, HBO seems to be really getting their shit together for the next year or so.
Remember five (?) or so years ago? HBO had Carnivale, The Sopranos, Deadwood, The Wire, and Six Feet Under--a freaking amazing lineup. Now, it seems HBO is entering that second wind. We have Treme, we're going to get Boardwalk Empire, and then we'll be receiving Game of Thrones next year.
Good... 'effin... goodness.
Granted, True Blood and Big Love and such shows have tided me over, but none have really struck that insane obsessive cord in me. However, with this line up I think we can say HBO is gonna be back in prime form, ladies and gentlemen.
