This latest instalment of Rodriguez's hugely enjoyable franchise has the added spin of being almost entirely in 3-D as pint-sized secret agent Juni Cortez (Sabara) has to rescue his sister from a virtual reality video game that is also threatening to warp the minds of the planet's teenagers. Visually, it's a treat - Rodriguez makes the most of the multi-dimensional novelty to fling cars, knives and assorted other objects at the audience with impressive fervour - but it somehow lacks the sparkle and the wit that made the first two so much fun for kids and adults alike.

Stallone hams things up thoroughly as the evil Toymaker, and there's a bunch of amusing celebrity cameos from the likes of George Clooney and Salma Hayek. But the film itself falls into the classic summer movie trap of selling itself on eye candy at the expense of everything else.
