Downton Abbey looks beautiful and is great fun to watch, but the character motivations are filtered through a 21st Century sensibility. In real life Lady Mary's reputation probably would have been ruined after her night with Mr. Pamuk. The whole affair about the youngest daughter and the chauffeur is silly (and stereotypical) and in general Lord Grantham and his family are too familiar with the staff.Even for an old family retainer Grantham is remarkably free with his opinion.
Eric StoIt's interesting to me that some of you suggest that Downton Abbey gets it wrong in some aspects. Naturally there is an enforced dramatisation otherwise we should most probably fall asleep watching it. One too easily forgets the advanced feminism that was all the go in the Edwardian days in the form of the Suffragette movement.
I am sure that Lady Mary's reputation would have been besmirched - had her affair become common knowledge. It didn't.
The case of the youngest daughter and the chauffeur - these things did happen and it was correctly handled in my opinion as to how the Earl reacted.
As to over familiarity with the household. I don't think so. I would merely put it down to the now old fashioned way of respect given down as well as up - together with good manners and concern. Of course the Earl Grantham and his family may have been in a minority when it came to the way they treated those in service - but the more enlightened would have been similar as shown.
All things considered I take delight with "Downton Abbey" as it reminds me of the "good old days"

- and I of course have much delight in whatever the Dowager Countess comes out with. (Reminds me of my own Grandmother who was born in 1887)
Westerns, Musicals and some other films - I don't really worry too much about as I just take the sillyness as it comes and wallow in it with glee. However if a fillum purports to carry on with a degree of sincerity I do take umbrage if I espy a plastic cord hanging out the end of a telephone or a tape recorder on a desk in 1931 - things of that ilk. That's just being careless.
