Us Rating: ****

With six Emmys and an endorsement from Will and Kate, the delicious period drama returns, and is even more grandly addictive. England, 1916: The aristocratic Crawley family and the many servants on their estate can't escape the tragedy of World War I -- but they still have time for juicy romantic travails and stunning treachery. Eldest daughter Mary (Michelle Dockery), for one, pines for cousin Matthew (Dan Stevens), who now has a fiancee! All the story lines, from torment on the front to a blackmailer's surprising arrival, unfold at a pulse-heightening clip. Magnificent! (PBS, 9 p.m.)
