A stately country house, a noble family, and a succession crisis are the backdrop for Downton Abbey. Lord Grantham sees his family heritage, especially the grand country home Downton Abbey, as his mission in life. The death of his heir aboard the Titanic means distant cousin Matthew Crawley, a Manchester lawyer, suddenly is next in line and accepts moving onto the vast estate with his even more modernist, socially engaged mother, who clashes with his lordship's domineering, conservative mother, the dowager countess. Marrying off the daughters is another concern.
Very early on, it seemed the show was going to be an unapologetic ode to this type of living and the notion of noble masters and humble servants, but things proved to be more complicated than that.
Compulsively watchable from the get-go, Downton Abbey fulfills the Masterpiece designation more faithfully than just about anything else to grace the PBS showcase in years.
