The Wall (BBC3) is a shiny, shouty, corner-cutting studio show. Producers didn't bother with scripts or jokes, depending instead upon the laziest sub-Boosh surrealism ("Hey, let's have a talking... wall?"). All it had to declare was its star guests (We Are Klang, Jonathan Ross) and its "hot property" presenter Alexa Chung – good job everyone's forgotten about Get a Grip, the woeful TV double act she and Ben Elton perpetrated last year. Well, almost everyone.... Here, she gets a second chance. For all her cool, she turns out to be charmingly reminiscent of a friendly prefect at an expensive school – forever balancing her innately posh, clever confidence against a cringing display of self-deprecation. What is her talent, exactly? It's hard to say, but like all the best prefects, she inspires people to want to be her, which is, I suppose, a kind of talent. Anyway, while you'd never call The Wall good, it's certainly better than Lily Allen and Friends.
