I enjoyed this Tube review of Detectorists as it was an off-the-cuff effort by an American who sort of stumbled his way through it, but with genuine love of the programme.
Coincidentally, I have many friends in the States who are now watching it on Netflex and adoring it for it's 'Britishness'.
Somehow, by hook or by crook, they must find their way back to the field where the Saxon boat burial lies, to go full circle - as that was the original quest and it should end there IMO!
