Review: Matthew's death may inject some life into 'Downton Abbey'

Expect Season 4 of 'Downton Abbey' to return to the original themes of change and endurance, handled with strength and mettle by the series' women.Across the land, a great keening has arisen for the large number of main characters recently killed off on shows as disparate as "The Walking Dead," "Scandal" and "Game of Thrones." How ruthless have we become, the hand-wringers wail, how reckless and desperate in our need for tweetable moments and first-week ratings.
