With its fifth feature-length adventure, this franchise continues its preposterous journey at full tilt. As before, it's the zippy writing, lively vocal work and colourful animation that hold the interest. The story is merely a framework on which the cast and crew can hang a series of rapid-fire jokes, pop culture references and nonsensical action sequences. And it's still mindless fun.

After their previous escapades, the expanding herd of prehistoric critters is living a happy life together, thinking about love. Mammoths Manny and Ellis (voiced by Ray Romano and Queen Latifah) are struggling with the idea that their daughter Peaches (Keke Palmer) has fallen for the too-cheerful Julius (Adam Devine). Sid the sloth (John Leguizamo) has just been dumped and feels like he'll never find a partner. And tigers Diego and Shira (Denis Leary and Jennifer Lopez) worry that their violent nature will make them terrible parents. Then suddenly there's a bigger issue to worry about: a giant asteroid is heading for Earth, threatening them with extinction. With the help of nutty weasel Buck (Simon Pegg), they come up with an idea to save the planet. They also discover a magical place called Geotopia, ruled by the groovy Shangri Llama (Jesse Tyler Ferguson).

Yes, the plot is utterly insane, especially as it is driven by the antics of franchise star Scrat, who discovers a flying saucer in the ice, activates it and heads into space, where his acorn-hunting antics trigger all sorts of mayhem back on Earth. But then this series has never had anything to do with science or biology, throwing random animals together (the dinosaurs make another appearance) for comical value while cranking up whatever suspense the writers can think of to add some momentum. They also of course pack scenes with sweet "family values" moments, plus a sideswipe at climate change deniers who refuse to acknowledge the possibility of impending doom.

When the ice shelf suddenly cracks in two, mammoth Manny (Romano) finds himself adrift with sabre-tooth Diego (Leary), sloth Sid (Leguizamo) and Sid's toothless granny (Sykes). But as they attempt to get home, they're waylaid by a pirated iceberg sailed by Captain Gutt (Dinklage) and his scurvy crew.

Meanwhile, Manny's wife Ellie (Latifah) and their mildly rebellious daughter Peaches (Palmer) are trying to outrun the shifting continental plates. And the film's real star Scrat is on a hunt for a hidden acorn treasure.
