Damian Lewis' departure gave Billions a "much-needed kick in the a**" in Season 6

"For five seasons, Billions has been a war of attrition between Chuck Rhoades (Paul Giamatti) and Bobby Axelrod (Lewis). Now it’s a war of attrition between Rhoades and Mike Prince (Corey Stoll), the 'ethical' corporate raider who ran Axelrod into exile and took over Axe Capital," says Dustin Rowles. "The 'ethical' part is what has made this season so much fun, because the thing with Axelrod was that he was shady AF, everyone knew it, and the question was: Can he get away with it? After a few seasons of that, though, it felt like Billions was mostly spinning its wheels, moving the pieces around the chessboard until, at the end of every season, either Rhoades or Axelrod would queen a pawn and it would start all over again."
