 One of the movie's subtlest achievements is the way it clues us into Janet's perspective, even as it keeps Janet herself at a bit of a distance. Much of the time, we're studying Janet through Lacey's eyes, and what's uncanny is the way Baker captures a sense of the girl's growing disillusionment. That intensely specific moment when a child begins to see even a doting parent in a clear and not always flattering new light.
