I was looking forward to this show since I saw the trailers for it towards the end of the summer, and from the start of Episode 1 it has certainly exceeded my (rather high) expectations!
I may be slightly biased as I used to be a Detectorist in my college days some 20 years ago now, and so I immediately picked up on a lot of the behaviours and in-jokes that Mackenzie has scattered throughout the shows ("Are you metal detectors?" 'No, THESE are the metal detectors, WE are the metal detector-ISTs..') to little quirks of behaviour that I myself was guilty of (agreeing a mutual "Detectors Off" time at the end of a days hunting, or indicating an important find by performing an impromptu dance).
This is a comedy that everyone should enjoy though, not just detectorists, although you can tell Mackenzie does love the hobby. I've often thought one of the corner stones of a good comedy (or drama in general) is to have characters you can relate to, and that work well together on screen. Andy and Lance (Toby Jones) have this in bucket loads, and they do come across as being very close, old friends.
There's plenty of side-stories woven into the main thread, that keep you guessing and asking questions as the shows progress (Will Andy get together with Sophie, what/who lies buried in the paddock, why does Lance still hold a candle for Maggie..) but not enough to distract from the main plot.
All in all this is fantastically written/directed, original comedy with a great choice of actors (Simon Farnaby, Pearce Quigley..) and to top it all it features a brilliant soundtrack throughout by Johnny Flynn (or Johnny Piper if you're short sighted.) I find myself looking forward to Thursday Nights at 22:00, and if I'm honest I'm struggling to remember a show that I could last say that about, possibly Rev series 3, or Toast of London.
