Fortunately, “Severance” returns to Apple TV+ on Friday, and its makers seem to have used every second of the absence productively. The season takes new turns while remaining the most ambitious, batty and all-out pleasurable show on TV, an M.C. Escher maze whose plot convolutions never get in the way of its voice, heart and sense of humor.

Since it debuted on Apple TV+ in 2022, we’ve been patiently waiting for the return of the show for Season 2 and now it’s finally here. But maybe you didn’t watch Season 1 when it premiered. Maybe you’ve heard all the talk about the show — or you just got Apple TV+ — and you want to dive in with Season 2.
