Detectorists

Detectorists, BBC Four's fine comedy, came to the conclusion of its second series in the only way possible, with Lance (Toby Jones) finally doing a "gold jig" after the discovery of the medieval trinket that has tantalised in the title sequence. After weeks of wandering field and hillside with their "coils to the soil", this was no more than he and his metal-detecting confidant Andy (Mackenzie Crook) deserved. Jones gives his grins away so sparingly it is well worth the half-hour wait to see his doleful features transformed. Detectorists remains the most likely winner of any "sitcom on an unlikely theme" award, but it works because of the unfailing Don Quixote meets Countryfile tone of Crook's script and direction. "Ambition's overrated," suggests Lance as he clambers over a stile - leaving Andy, with baby Stan papoosed, to struggle with yet another fatherly obstacle - but nevertheless keeps on digging up 1980s Fanta-can ring pulls in the hope of finding the Staffordshire hoard.

Appropriately enough, the long-awaited detectorists' rally - bringing together the Uxbridge Unearthers, the Letchworth Locaters and the Romford Recoverers - passed mostly without incident, except for the troubling appearance of a rogue detector, a "nighthawk - scum of the earth" at the dig site. Still, in among the sedimentary strata of English despond there are always nuggets of hope: Lance found common ground with his newly discovered daughter; Andy the reed-thin resolve to try a new life for size. "We are all looking for gold," is one of Lance's certainties. Another, eminently employable is "when in doubt dig it out".

What a great show this has been; its late summer vibes, subtle wisdom and inklings of melancholy making it a Nick Drake among sitcoms. As the series closes, Lance, Andy et al have reason to be optimistic. Lance has confined himself to leaving a mere eight messages for his daughter Kate, and Peter the "nighthawk" looks to have been vanquished. All comes to a head at the club rally, but quietly spectacular ensemble performances (especially from Sophie Thompson as Sheila) create a perfectly pitched tone throughout.

When I heard the premise of Detectorists (BBC Four, Thursday) -- middle-aged blokes potter about the countryside obsessively looking for buried treasure -- I presumed we were in for a spot of easy satire where the author's message would be something like 'Get a life, you losers.' In the event, this tender, kindly show has portrayed its characters as almost heroically indifferent to modern social fashions and demands. (And I bet there are far more of such people about than we generally see on television -- except of course on Only Connect.)

This perspective was duly reflected in the real author's message that came on Thursday when Andy (Mackenzie Crook) worried aloud that he wasn't ambitious enough. 'No shame in that,' his friend Lance (Toby Jones) reassured him. 'Ambition's overrated. All these people reaching for the stars and striving to be the best. It looks exhausting.' Not coincidentally, Crook, who wrote and directed Detectorists, turned down the chance to be in Pirates of the Caribbean 5 so that he could make the show.
