Very Important People

Will Channel 4's new takeoff show take off?

How will the broadcaster's new impression show compare with the classics of the past - and how will it deal with modern social sensibilities?

In the 70s, audiences laughed in appreciative recognition as Mike Yarwood impersonated a range of public characters, even including trade union leaders. With latterday cultural fragmentation and the thin spread of increasingly nondescript "celebrities", the job of an impressions show such as this, starring Morgana Robinson and Terry Mynott, becomes all the harder. It is telling that they often have to announce who it is they're doing. Still, this is as capable as could be expected; in the first episode, Bear Grylls tries out his survival skills in the suburbs, while David Attenborough studies at close hand the remarkable animal that is Frankie Boyle.

From Spitting Image to Dead Ringers, satirising powerful public figures through mischievous impressions has been a popular shtick among British comedians. But Channel 4's new sardonically named sketch show, led by able newcomers Morgana Robinson and Terry Mynott, subverts the familiar blueprint. Like Bo Selecta's less surreal cousin, it opts to target C to Z-listers - products of ITV2 celebrity filler, the blogosphere and reality TV.

By design, this is a dangerous game, often relying on an audience obsessed with the kind of inane "celebrity" culture it seeks to send up. So while it's just about possible to relate to a sketch involving ex-EastEnder Natalie Cassidy in a faux reality show called I'm Doing This Now - "just hosing down the bins, really" - a mocked-up musical with Joe Swash and Stacey Solomon falls flat.

Ultimately, it's the humour involving better-known subjects - including uncanny impersonations of Gordon Ramsay and David Attenborough - which keeps Very Important People afloat. It's a brave experiment, taking a deserved swipe at vacuous popular culture norms. But will people see the funny side?
