So many of the most emotionally powerful moments in the Pixar movie canon have to do with the passage of time through a life, and the passage of a life through time. Sometimes that life is represented by a doll, as in the heartbreaking “When She Loved Me” flashback montage in Toy Story 2 or the even more composure-destroying ending of Toy Story 3. Sometimes it’s a robot, as in the sublime first third of Wall-E, a near-silent meditation on loneliness and loss. And sometimes the life is one that’s more recognizably like our own, as in the entire novel’s worth of insights about love, marriage, and mortality packed into the less-than-five-minute-long montage near the beginning of Up. The happy endings of these movies—like the happily ever afters of traditional fairy tales—aren’t just feel-good story resolutions. They’re affirmations of the value of hope, resilience, and human (or doll or robot) connection, even in the face of certain disaster.
