When we last saw the crew of the USS Callister, they were left to explore the whole universe of the video game "Infinity." This is the first direct sequel to an episode of "Black Mirror lookmovie." This turned out to be both a boon and a bane. The majority of "Infinity" players want to murder them and steal their in-game money, which keeps them alive. When the real world begins to reveal their illicit existence—actual AI in a game that should only be avatars—Walton tries to hide it, and Nanette tries to save them. Unquestionably, it's a fun episode, but it seems a little overflowing with ideas, attempting to defend its existence with a few too many twists and thematically driven jumps.
