Is it a play? Is it a political satire? Not really - it's Rik Mayall, not so much pushing the boundaries of taste as kicking them in their tenderest parts.
The idea of reinventing Mayall's Thatcherite monster Alan B'stard as not merely a Blairite MP but the covert architect of New Labour is, to be fair, pretty droll.
The proposition that the logical extension of Thatcherism is Blairism is one which will strike a sympathetic chord with many. The actual show, however, makes the knockabout political farce of Anyone for Denis? look like Chekhov.
Alan is up to more of his old tricks with a hand in seemingly every dodgy deal in national and international affairs.
Whether it's plotting the downfalls of Blair and Brown, double-crossing both Condoleezza Rice and terrorists over WMDs, trafficking Albanian sex workers or hiring a contract killer to blow up his divorce-seeking wife, his boundless spirit of enterprise, matched by a total absence of moral scruple, is seemingly irresistible.
The trouble is that the entire absence of redeeming features makes Alan a distinctly one-dimensional character, performed by a comedian who only has one gear: full-on.
The other characters - the downtrodden Old Labour junior minister whose shameful secret Alan knows, the Blair-babe totty and even Condoleezza, who bursts in Emma Peel-style through the french windows accompanied by security guards, are mere cardboard cut-outs.
Mayall is seeemingly much-aggrieved that he can't get Alan on TV these days. But TV has given us The Thick of It, an equally cynical take on Blairite politics but one which offers a far more rewarding response to it than simply sticking your fingers down your throat - though Alan, I'm sure, would much rather stick his fingers down someone else's.
