Even before Carson popped the question, this Christmas special was shaping up quite nicely. Heavy on the sentiment, sure, but that's what holiday episodes are for -- a fact that "Downton Abbey" hasn't always remembered. (Need I remind you of the Chrismas special that ended in an extreme closeup of Matthew's bloody, lifeless face?) For a moment there as Lord Grantham complained about his "tummy" pains, I thought more tragedy might be in store. Happily, it turns out he's got an ulcer and the only "tragedy" is that his lordship has to lay off the hooch for a few months so that by the time Christmas rolls around, he's tanked after a single cup of punch. Steady on!
