James Campbell's Shut Up Stupid

James Campbell's latest offering calls itself a 'black experimental comedy', and you'd be right for wondering if this is suitable for children. Much effort has gone into scripting the warped chronology and fourth-wall antics of the plot, but they're wasted on an audience that's not too fussed about such heady concepts.

The two leads specialise in a kind of simpering lunacy and cartoonish tenacity and there are moments of 'mild peril' - one scene involving a knife to the throat certainly has some parents on edge - but the material is largely family friendly.

Older children may appreciate the lay analysis of a parent's mind, while their younger counterparts might enjoy the healthy dollop of scatology in the midsection, but this just isn't enough to make a passable show. Kids are hard enough to please at the best of time but thinking this kind of caper is good enough is just, well, stupid.
