Mad Men is Mid-Century America Kabuki, with its own kind of stylized costumes and a series of carefully constructed and elaborate tableaus where nothing is ever obvious and everything promises another layer of meaning left behind for us to peel away. Spoiler Alert: Here's a recap of the episode, but don't watch if you haven't seen it yet.
There's an interesting special interactive feature "Seeing History in Mad Men" from The New York Times, which has been thoroughly covering the return of MM with several recent articles. Last week they spotlighted different aspects of the series here, as well as looking into the use of period-appropriate language on the series with this "Mad Men-ese" story. Alessandra Stanley gave a look forward to Sunday's premiere here, and Ginia Bellafante wrote about it today.
Vanity Fair has a nicely detailed piece by James Wolcott, and The Onion's AV Club has a great overview of the episode here, too, and a few enlightening videos. I count myself among the folks who already knew what Peggy and her coworkers were riffing on with their "John...Marsha" routine, but it's evidently not exactly a universal pop culture reference point.
I also love Advertising Age and their coverage of the premiere episode, which of course contained a major scene involving the industry publication preparing a story about Don Draper et al's new agency. Rance McCrain writes about the portrayal of Ad Age in the show, and Larry Dobrow offers up a media industry-centric look at the episode. Both are great reads.
If you've seen the first episode, you know that Mr. Draper got his freak on a bit, as seen below. Again, Spoiler Alert!
Be sure to visit AMC's Mad Men site for much more information and behind-the-scenes features that will add to your appreciation of MM.
