Storyboards
The series's "masterful sense of pace", wrote James Whitbrook in io9, allows the series to subtly integrate elements of foreshadowing and worldbuilding into individual scenes that almost imperceptibly make an overarching dramatic narrative emerge from what might appear to be "monster of the week" episodes. The series's conceit of telling a complex story from a child's perspective means that its exposition remains "artfully restrained, growing in ambition with the series" and Steven's character, in the view of Eric Thurm in Wired.
