highclere-castle-It’s great to have “Downton Abbey” back on “Masterpiece Classic” (PBS, 9 p.m., check local listings), though public television seems set on messing with the magic by its odd manner of presentation, lumping the first two episodes together tonight makes it an unwieldy and nearly exhausting exercise that messes with the pace.

Even as the new Mrs. Bates continues her quest to find her jailed husband innocent, Daisy becomes slightly revolutionized. There are new faces downstairs as well to add the intrigue.

Future installments of the “Downton” season will be the proper hour in length until the finale next month, which will be back to two hours.
