I haven't seen Maniac, will give it a try. I agree that Severance is not something super original, it made me think about the Homecoming or some episodes of Black Mirror. But it's well made and I enjoyed it a lot, the music of the intro, acting (John Turturro and Christopher Walken are amongst my favourite actors).My buddy loved this. I watched half of it. It was fine. But it felt too much like Maniac (Jonah Hill, Emma Stone), Lost (to a lesser degree) and other similarly thematic productions.
