Tracing the 70-million-year old journey of Pachyrhinosaurus Patchi (Long) from runt of the litter to king of the herd, with the help of a sassy Alexornis named Alex (Leguizamo).
It is a depressing world we live in now where the BBC would put its name to something as insipid, bloodless, pseudo-educational and offensively anthropomorphised as this brand-extension of the once-mighty Walking With Dinosaurs series. Especially when you consider that all the hard graft and impressive craftsmanship on the behalf of the visual-effects artists (laying wonderfully textured and expressive CG beasts over real locations) has been wrecked by the decision to insert chirp-pop songs and voice the principal dinosaurs. Relentlessly so. Barely a moment passes where neither Justin Long nor John Leguizamo lamely quip or make a poo joke or pointlessly narrate events that a three-year-old could have followed in a direlogue-free cut. Note to the film-makers: children are smarter than you evidently think.
An object lesson in how one awful creative decision (sassy voiceovers, flavourless pop tunes) can wreck a movie that might otherwise have been watchable. Wait for the Blu-ray and watch it with the sound off.
