"Reign" takes place centuries before "Downton Abbey," but many of the same dilemmas still face the characters in both shows. Loosely based on the real life of Mary, Queen of Scots, "Reign" features a determined young woman who, despite being her father's eldest living child, struggles to take the power that should come with it — sound familiar? Eldest daughters of both shows also find themselves pushed toward marriages with men who are heirs themselves as a means of consolidating their wealth, and both unexpectedly fall for their would-be husbands despite plenty of drama. While the story of Mary, Queen of Scots, may not have a happy ending in history, the glamorous series will suit "Downton" fans looking for more well-dressed politicking and romance.
