If you speak of the amazingly awesome show Brimstone, you are my new favorite person.
Brimstone is one of the best shows ever on TV. Witty, intelligent, and intense. People say Firefly got a crap deal from Fox, but Brimstone got it worse, having been cancelled with only a handful of episodes aired and then largely forgotten.
It is, however, fantastic. John Glover's portrayal of Satan pretty much defines the Devil for me. He is the Prince of Darkness in every way. The way they used Christian mythology to create such wonderful stories is incredibly impressive.
I lament quite a bit that it will never, ever have closure, unlike Firefly.
