Parents need to know that "The Good Dinosaur" - Pixar's lush animated prehistoric saga that successfully melds "Finding Nemo" and "E.T." - has stunning visuals, clever humor, strong messages, and some scenes of violence and peril that could certainly frighten younger/more sensitive viewers. (Spoiler alert!) Apatosaurus Arlo is separated from his family after a flash flood that claims his father (a series of events that could definitely upset kids); plus, carnivorous, sharp-toothed beasts attack Arlo and his human friend, Spot; thunderstorms bring massive explosions of deadly water; and the heroes barely survive a dangerous ride down a waterfall.
