Some dramatic changes are occurring in the lives of Manny the mammoth, Sid the sloth and Diego the sabre-toothed tiger. Manny is preoccupied with a pregnant partner, Diego’s lost his mojo and is having a midlife crisis, and lisping loser Sid… well, is it any wonder he doesn’t have a family of his own? Following a minor tiff, Sid wanders off, falls through the ice and discovers three dinosaur eggs which he adopts – until big mama Rex comes trundling into the frame. In a nod to ‘Journey to the Centre of the Earth’, the rest unfolds in a Cretaceous underworld where Manny and Co – aided by a cocky new weasel character – attempt an audacious rescue.
Some have expressed displeasure at the design and voices of the leads. I disagree – but I do think Simon Pegg’s Artful Dodger-like weasel is a vocal cliché too far. Similarly, some of the anarchic, comical segues featuring Scrat the squirrel and a newfound love are beginning to feel overfamiliar. As with the two earlier films, it’s all a mite disorderly in tempo but often highly amusing and great fun in the main.
