If there's a single eternal truth about Showtime's Billions, it's that no matter how rocky the season itself might be, the finale always delivers. Take this season for instance. The show has struggled to hit its previous highs — for me it's less because of the departure of Axe (Damian Lewis) and more related to the fact that the great ensemble cast has taken a back seat throughout much of the season — coming through with some solid episodes here and there, but never quite offering up the gripping twists and turns of previous seasons.
