Angsty maids and groomsmen accompanied with wealthy family drama propels the plot foreward...but hot men in period clothing also doesn't hurt.
Oh and tossing Professor Mcgonagall in there is also a total score. Meet Violet, Dowager Countess of Grantham
The major bonus?? They are in the middle of season two so you can have a mini marathon of season one...check it out at PBS. *sigh* cheers to the amzingness of Edwardian English dramas, never failing to satisfy my inner romantic.
