All in the Best Possible Taste with Grayson Perry, Channel 4, review An intelligent documentary was to be found on Channel 4 - which might sound surprising until I tell you it was All in the Best Possible Taste with Grayson Perry, one of the TV highlights of the year so far. Over the past three weeks, Britain's most-famous transvestite potter has been exploring the taste of the country's different social classes, before turning his findings into a series of tapestries. But when I say "exploring," I don't mean it in the traditional television sense of "making a few generalisations that he knows we all agree with anyway." Instead, Perry gives every impression of thinking carefully about what he sees - even to the point of changing the opinions he started out with. More controversially still, he seems to be trying to understand people different from himself, rather than simply sneering at them. In yesterday's final episode, Perry reached the upper classes. After some cheerful knockabout stuff at polo matches and the like, he visited various stately homes, where he soon realised that, like most Brits, he's still a sucker for faded wall hangings, bubbles in window glass and all the other signifiers of old-style architectural beauty. He was also aghast that many of these houses are being bought by nouveau types keen to redecorate in a more celeb-friendly style. And there, I'm fairly sure, is where most presenters would have left it. Perry, though, once again interrogated his own responses with an affable ruthlessness. After all, where did we get the idea that old sofas and Agas are innately better than floodlit front doors and big tellies? Is it just that we instinctively prefer old stuff? And if it is, remember that when they were first built, places like Blenheim Palace were pretty blingy too. The conclusion to the whole series was that "good taste is that which is approved by the people around you." Out of context, perhaps, this might seem a bit glib. After three episodes of clear-eyed but never po-faced analysis, it felt genuinely hard-won. It was also the only possible explanation for everything we'd seen in a hugely entertaining, and often revelatory, piece of television.
