Suddenly, Billions is one of the most delightful fucking things on TV. Hey, don’t ask me, I just work here! But after two episodes including tonight’s rip-roarin’ “Dead Cat Bounce,” the show’s second season has turned the first outing’s (very) occasional flashes of wit and heat into a strobe light designed to trigger the pleasure center of your brain into some kind of awesome epilepsy. The schemes and plots are dizzying but perfectly constructed, the main characters are holding their own, the supporting players bring down the house, and the whole thing feels like almost a brand new show. It’s too soon to tell if this will be as big a turnaround as series like Halt and Catch Fire and The Leftovers experienced, and that may be an apples-to-oranges comparison anyway—they’re far more serious dramas, for one thing, and for another they were already on the upswing by their first season finales, while Billions stumbled through that particular finish line. But I’m enjoying pretty much every second of screentime, and it’s one of the young year’s most pleasant televised surprises (Warren Beatty and Faye Dunaway notwithstanding).
