LONDON (BBC): The series finale of BBC One’s costume drama re-make Poldark was watched by 5.9 million people on Sunday night, just over a quarter of the TV audience. Competition included ITV detective drama Vera’s two-hour finale starring Brenda Blethyn, seen by 4.9 million, and film The Impossible on Channel 4.  A second series of Poldark, starring Aidan Turner as Ross Poldark, has already been commissioned. The actor won legions of fans as the brooding, scythe-wielding Cornish hero.
