But, surely, the comedy is too broad, the situations too exaggerated to call it brilliant? Ali Mossop, for example, goes from being a downtrodden worm into a model of self-confidence in barely the blink of an eye. Jones responds with an illuminating insight. 'But it's a fairy tale, isn't it? There's an ogre - that's the father, Hari. Ali has to undergo several trials to win his girl - that's a sort of Pygmalion theme. And there are even ugly sisters, who, in this case, happen to be beautiful.'
