In a clip shown at D23, the audience got to see just how emotionally resonant this cinematic concoction was going to get. In it Arlo is hanging out with his new human friend when he wistfully says, “I miss my family.” When the boy seems to not understand “family,” the dinosaur sets up a series of sticks, each one representing a member of his nuclear next of kin. Just when he starts to think Spot still doesn’t get it, the boy makes his own stick family then knocks the members over and buries them in the ground to show their passing. Arlo does the same with the stick that represented his father.

From our first glimpses, it seems like The Good Dinosaur will be a painful, emotional roller coaster ride, and we couldn't be more excited. Sob into theaters to see The Good Dinosaur on November 25.
