Animated feature from Disney graduate Bluth follows the fortunes of orphaned Brontosaurus Littlefoot, who loses his mum to the claws of a nasty Tyrannosaurus Rex before teaming up with a gang of similarly parentless wee dinos to undertake the hazardous journey across country to the safety of the Great Valley. Classically drawn and chockful of edifying moral lessons, this is solid entertainment perfectly tailored to the demands of its target audience of very young children.
