John Krasinski may still be in an early chapter as a filmmaker, but he’s already carving out a nice reputation for having a fantastic knack for fantasy. With A Quiet Place, he was able to create a sensory-deprived moviegoing experience as a distraction to explore the bounds of his fantastical horror. In his latest film IF, a much more family-friendly vehicle, Krasinski has fun with the boundless limits of the imagination.
