‘Downton Abbey’ strong in second season
In the show’s second season, the stories grow richer - and funnier
Like fine bourbon makers the Brits prefer to craft their TV shows in small batches. And when it comes to “Downton Abbey’’ the results are similarly worth savoring. The Carnival/Masterpiece producton begins its long-awaited second season on WGBH Sunday at 9 p.m. and dedicated viewers of the first set of episodes will be delighted by the continuing adventures both upstairs and down in the Earl of Grantham’s grand household.
