Shameless bump here.
BTW It's not a comedy at all, but one of the most popular Dramas ever. In fact, in the USA, it is THE most popular program ever on PBS.
Locally, the repeat of SE1 through SE3 was interrupted for pledge week but, "Return to Downton Abbey" was aired. It was a review of SE1-SE3, with a preview of SE4, and comments by most of the cast and Julian Fellowes. I archived it and will watch after I see SE3. (Yes, I took peeks at it.)
SE3 will be aired starting this coming Sunday. And SE4 will begin on Jan 5th. Seeing all four seasons consecutively is an epic event for a first time viewer, and I'm sure waiting for SE5 will be painful! But wait we will.
A year ago, I never would have thought it, but I'm hooked and loving it!
