The Living and the Dead (2016)

It opens in the Somerset village of Shepzoy on the summer solstice of 1894, as a pioneering psychologist brings his wife home to modernize the family farm and finds the old customs very much alive. Corn dollies, menacing scarecrows and the memory of a hedgewitch drowned by the previous generation sit alongside a run of hauntings his science cannot explain. Colin Morgan plays the doctor's certainty cracking with real skill. The BBC never renewed it, but the single season wraps up on its own terms, so there is no cliffhanger to regret.
