Everything I've read suggests it's overly pretentious and over wrought/heavy handed. But then again, that describes most of his stuff. Despite being such a history/politics nerd, I couldn't get past the first few episodes of The West Wing. The dialogue feels too much like him dictating how things should be, how figures should act, etc.
You can only be an asshole in Hollywood for so long before people jump down your throat, and it seems like he has reached the end.
