HBO has made some of my favorite TV shows: Rome, Carnivale, Deadwood and my current obsession, True Blood. This is likely going to be another show along those lines. It’s based off of a series of fantasy novels. I haven’t read the books yet, but people at io9 tell me I should.
The cast of this show is quite good. It’s more like the ensemble of Rome rather than the True Blood gang. Obviously Sean Bean is the star but Lena Headey, Peter Dinklage and Nikolaj Coster-Waldau are pretty famous too.
