I learned that this was upcoming last fall, and it is basically the only thing that can make January palatable for me.
The only little blot on my happiness is this article from The Daily Mail, which claims that two hours have been cut from the production because we Americans are too dumb to understand it in its entirety. Now, I am the first person to admit that 95% of American TV is trash, but that's just rood. AND, they negelected to add that the production is shown here on PBS, which has no ads, while it ran on ITV in Britain and had two hours of ads. And also that PBS viewers are SMART and can follow a British serial, no problemo.
Here's a rebuttal article.
Anyway, I hope you watch this too so it can be the bright spot in all of our January. "Downton Abbey" will air on Sunday nights--January 9th, 16th, 23rd, and 30th.
