The crew of the USS Callister is left to explore the full universe of the video game "Infinity" when we last saw them in the first direct sequel to an episode of "Black Mirror lookmovie." As it happens, this was both a boon and a bane. To keep them alive, the majority of "Infinity" players desire to murder them and steal their in-game money. Walton tries to hide their illegal existence—actual AI in a game that should only be avatars—but Nanette tries to save them when the real world begins to reveal them. Unquestionably, it's a fun episode, but it looks a little overflowing with ideas, attempting to defend its existence with thematically laden jumps and a few too many twists.
