Coming to "Masterpiece Theater" Sunday is a new production of "Poldark," based on Winston Graham's novels of love and family, copper mining and class war in late 18th century England. You might want to be there when it arrives if passionate, period British literary melodramas are at all your thing.
One can't properly call it a remake, given its bookish origins, but for all intents and purposes the new production proceeds from an earlier series, a small phenomenon on both sides of the Atlantic that created a tourist industry in Cornwall in the 1970s, long before "Doc Martin" became synonymous with that neck of the British coastline.
