This and Rome. I know there is no hope for Rome since the sets burned down, but god damn did they have a show there. Now they are scrambling to replace game of thrones, and they already had a BETTER game of thrones they cancelled. So frustrating. But I'd kill to see Rome done out with the same actors/writers as they had originally planned. (S2 was supposed to end with the death of Brutus. S3 was Antony's death. Then it was going to be the tension between Agrippa and Octavian, as well as the rise of Christ in Jerusalem and the rebellion there.)
Honestly to this day Rome and Deadwood are my two favorite shows ever. Rome is one of the few shows I will watch every year without fail, and I always seem to find something else in it. Deadwood I'll watch most years, and sometimes the Sopranos. It's amazing those shows have held up so well in the golden age of TV, but talk about lightning in a bottle with Rome and Deadwood.
