Spy mom Marissa (Jessica Alba) hopes to leave the business to live a normal life with husband Wilbur (Joel McHale) and his twins Cecil (Mason Cook) and Rebecca (Rowan Blanchard).
The Timekeeper (Jeremy Piven) has unleashed terror on Earth. He's devised a plan to steal time. In fact, clocks and watches simply speed up - it's less stealing time than hurrying it along, except none of the characters display signs of ageing. The twins are drafted into the Spy Kids Division to try to help their stepmother stop the Timekeeper before time runs out.
A number of tasteless pranks might make you nauseous. Be prepared for flying vomit, green slime and nappy bombs. That said, the kids have some really cool gadgets that would put even Inspector Gadget to shame. And a talking, martial-arts-fighting dog named Argonaut (Ricky Gervais) provides witty humour.
However, given all the time in the world, I still wouldn't want to sit through this one again. It's lucky the DVD version doesn't include "smell-o-vision". Cameos from the original spy kids - now adults - might be of interest to fans of the series.
