Would you rather watch TCM all night long or watch continuous season episodes of MadMen? I think I'd bend towards TCM...TCM movies are actually a "more real depiction" of the 60s, 70s... You know, kinda gives you a feel of the real deal...

Movies produced at that time tend to reflect a more homogenized or idealized view of the world of the day.  It's like the difference between a "Leave It to Beaver" view of America in the late 50's and early 60's and "Mad Men". 

Think of a movie like "Guess Who's Coming to Dinner" and contrast it with "All in the Family".  Which do you think represents a more realistic view of the "average" person of the time?  "Guess Who's Coming to Dinner" was ambitious but at the same time, self-important, trying to be a real "issues" movie.  This doesn't mean that real, thoughtful people weren't grappling with the issues of the day in a real and meaningful way - I just think there were more Archie Bunkers than Matt Draytons.

Which is the beauty of "Mad Men" -  Pete  would never have viewed his conversation with Hollis, the elevator operator, as being subtly racist, objectifying Hollis as a symbolic representation of all African Americans.  In that case, Pete is a stand-in for all the well-meaning people who really didn't have a clue.  In a 60's movie, Pete would have come across as well intentioned, if ham handed.  From the vantage of the 2000's however, the subtle prejudice he exhibits makes one squirm.
