I've found a new TV addiction until BSG is back on the air: Rome. You can get the first season on Netflix, and the current (second) season is playing on HBO.
It's quite a detailed show that seems to capture the grittiness of the time with an abundance of sex, violence, treason, plotting, politics and action.
+1 recommendation on Rome. By far the most intense television show ever made. The gore in the second to last episode in the first season is right up there with the famous Curb Stomp of American History X.
Oh man, that curb scene was too hardcore. It still disturbs me!
I tried to find this on HBO on demand, but not there. That totally bites.
