My father dislikes this series. I understand why; this is not an historic re-creation of the late 50's and early 60's. My father is of an age with Don Draper, he lived through these times, and he knows that they little resemble this series. The inaccuracies irk him. I understand his point, and I would probably feel the same way about a series that purported to represent the 80's.
It's funny that while people intuitively understand that futuristic stories are really about the present, they naively assume that stories set in the past are not. The show deliberately highlights things which we "moderns" find shocking - the young girl playing in the dry-cleaning bag, for example - but the time period itself is fundamentally a vehicle for plot and characterization. Anyone who imagines that this really is 1960 "as it was" is missing the point. Not that the directors are terribly clumsy about making the setting realistic, mind you - I swear they used all of my grandmother's furniture for the Draper home.
That noted, what I love about the series is the characterization. Don Draper is fascinating; Betty Draper is a bizarre mix of little girl, doll, temptress, and real person struggling to stay alive; I loathe Peter Campbell about as much as I can loathe a fictional character; and as for Peggy - well, no spoilers. Eminently watchable, intelligently written, periodically amusing, moving, and disturbing.
