Entertaining on every level. Great dialogue, acting, production and character development. I can't always keep up with the references to popular culture, but the ones I catch are smart, if overdone sometimes. Paul Giamati has grown in the role throughout the series, which was necessary, and ultimately rewarding. The dialogue is lean and the plot, for all its arcana of financial manipulation, is masterfully clear. I don't imagine this is really the way financial and political titans go about thiings, but it's so much fun, I don't care.
