Butting in to WORD the majority of this conversation, especially the bit about Joss writing about a Christian/religious character and not doing so hot. That's where Aaron Sorkin pwns Joss - he can write any worldview and have it resonate, no matter what his personal opinions are. See: Ainsley, Harriet Hayes on Studio 60 (which y'all should Netflix right now, just because it's Sorkin writing about TV. Not his best work, but Sorkin's mediocre is better than most people's best.)
