Disney films have a tried and true formula, and "The Good Dinosaur" is no exception. However, there's something rather soothing about the familiar, and when it's executed well, it's cinematic comfort food. The time-tested template is in full force in the latest Disney-Pixar flick: take one misfit youth, add parental peril and a journey away from home, where our protagonist learns a life lesson or two and displays some hard-won heroism.
