I'll look into Poldark. Outlander had kept our attention for a season.

Nothing will turn my wife off a show faster than a drawn out torture scene, and Outlander had a doosie at the end of season 1. Then, in the second season, the actors all jumped out of character, doing things they obviously shouldn't have done with little explanation (the newbie still being a newbie even though the first season she went to hell and back; the patriot not being a patriot for seemingly no reason at all), so the show became totally unbelievable very early in season 2.
