Here's a quick refresher on where things stand with Mark, Helly, and the gang The second season of Severance, which debuts tonight on Apple TV+, proves that the corporate sci-fi drama has still got it.

The acclaimed Apple TV+ series is making its long-awaited return. A second season was filmed over three years.

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.

While “Severance” has a wonderfully creepy-compelling premise, it’s a concept better suited to a movie than a multi-episode TV series.
