This week we had the Christmas special of Detectorists. Not that there was anything particularly festive about the so-called Christmas Special and it could well have been set during any part of the year. Toby Jones' Lance was front and centre throughout the entire episode which followed on from his discovery of an ancient medieval artefact at the end of the last series. The rather charming opening sequence saw Lance visit his find in a London museum and attempt to get his photo taken by the display. This to me was the highlight of a rather average episode of Detectorists which saw Lance try to dispel the supposed 'Curse of the Gold' that had befallen him since his recent discovery. Lance believes he has been cursed due to the fact that he hasn't been able to find anything since the end of the last series while he's also experienced a string of bad luck. The one primary reason I found this episode of Detectorists fairly mediocre was due to the fact that Mackenzie Crook barely made an impression throughout. Crook's Andy just happened to pop back from Africa in time to see Lance's disastrous display at the DMDC however their scenes together were limited. Part of the joy of Detectorists are the scenes in which Lance and Andy talk rubbish to each other whilst out metal detecting. Additionally there was very little continuity between this special and the series with no mention of Lance's daughter or explanation given as to why Sophie was nowhere to be seen throughout. On the plus side I did like the fact that Jones had almost thirty minutes to take centre stage and deliver what I thought was a masterclass is in awkwardness. The scene in which he completely ruins things with a potential new love is squirm-inducing however their later moment together was rather sweetly realised. This led me to ponder whether there will be a third series of Detectorists or if Andy will stay in Africa while Lance will finally find happiness with a lady mechanic. I'm hoping it's the former as Detectorists has become one of my favourite sitcoms of the last couple of years and I've got my fingers crossed that it doesn't end with what I found to be a rather underwhelming offering.

Mackenzie Crook's sitcom is something of an outlier in the current TV climate - a perfectly understated show which, in keeping with its subject matter, ever so gently reveals its treasures (from script to performances to photography) to those patient enough to wait. And patience is a rare commodity these days. In this seasonal special, Lance (Toby Jones) has lost his detecting mojo, prompting Russell to believe he is cursed: can he find it again in time for Christmas?

The delightful BBC Four comedy remains on good form, but prepare yourself for a different feel tonight as the metal detectorists tread barren, bare and cold fields.

As you would expect from this gentle series there are no earth-shaking moments.

Radio Times review

After the note-perfect ending to series two, it came as a surprise - but a lovely one - to discover that a standalone episode would light up the festive schedules. Lance, you'll remember, unearthed a major find, while Andy and Becky were all set for something similarly life-changing.

As we rejoin the lovable eccentrics of Danebury Metal Detecting Club, the wintry fields and furrows are proving barren indeed for Lance (Toby Jones), who's not even turning up the usual ring-pulls or "canslaw". Is there any more gold to be found in them thar hillocks?

Detectorists is so adept at cockle-warming that a winter episode is in many ways the ideal framework. Tantalisingly, Mackenzie Crook says, "We got to bring the story to London for some extra-special scenes." The show's ardent metalheads can't wait...
