I'm not a Downton fan, and think shows about the travails of the set upon landed aristocracy are, at best, blasé. (Edit: and how perfect and good the lords are, understanding, forgiving, getting along with everyone and removing social systemic strife... It's frustrating and I dislike it.)
But Downton was not "drek" it was well acted and shot at least and was made with care. Not for me nor do I agree with it overall, but it wasn't a "bad" show.
