This slow pace frustrated many fans of the games -- myself included. We know the backstory of Catherine Halsey (Natascha McElhone) and her use of kidnapped children for the Spartan soldier program that created the Master Chief. Except in this series, Master Chief is kept in the dark of his adopted mother and creator's sinister machinations, and the United Nations Space Command, humanity's authoritarian military power, is also unaware of Halsey's most dehumanizing, illegal experiments. His discovery of this scheme plays out rather slowly, and given that lack of action, the dramatic tension felt repetitive to knowing fans of the games' story.
