We haven't seen the film. Perhaps the fact that wild raccoons get to bludgeon domestic cats to death with golf clubs makes sense if you have, although - call us conservative - it seems to be a bit morally dubious for what is essentially a kids' game.
You mainly play alternately as RJ and Verne trying to steal food and not get seen by grown-ups, and that's about it. The levels scarcely vary in difficulty, although the locations change from 'behind the hedge' to 'just past the hedge' and then 'sneaking around in some unsuspecting person's living room', and you'll often find yourself repetitively and unrewardingly picking up bits of old food by walking over them. Although you can access extras and minigames, it's rather plain. Wee nippers who've enjoyed the film will likely give this some attention, but given the universal onset of Attention Deficit Disorder, it's doubtful.
