The title should be rendered with inverted commas surrounding the "magnificent". Harry Enfield and Paul Whitehouse comment jovially upon an selection of extreme sports stars who have parlayed YouTube notoriety into celebrity. Yes, it's a clip show, if one populated by two talents as opposed to the standard phalanx of nobodies. Unlikely to become regarded as either comic's defining work, but it should almost by definition be at least intermittently compelling - as folly, hubris and people skateboarding into dustbins always are.
