Second season review: “Currency,” the fifth episode of Billions’ shockingly good second season, is as ruthlessly efficient a storytelling machine as its predecessors. There’s not a plot beat that doesn’t reveal character, and there’s not a character revelation that doesn’t advance the plot. Guest stars—from the aforementioned Mike “Frenchy” Starr, to Dennis Boutsikaris, Danny Strong, and Jerry O’Connell as recurring rival hedge fund gurus turned potential allies, to Ritchie Coster of True Detective Season Two doing a sort of Mayor Chessani redux as a gambling-industry hotshot, to Mad Men villain Allan “Lou Avery” Havey as the boss of Christopher Denham’s superlative rat-squad investigator Oliver Dake—shine.” Sean T.
