I liked that episode.
Don was human...if ever so briefly. Meghan remained something of a spoiled brat, but at least a semi-compassionate spoiled brat.
The Pete/Harry argument was interesting if for no other reason than to show that the race card is hardly new.
Not being alive then, it was also interesting to me to see how they portrayed the MLK assassination. Was it really something that rocked middle-class white America? Granted, many of these folks aren't blue-collar middle class, but it sure seemed like this resonated far more throughout the city than I had ever imagined it did.
And if Don goes, he goes off that balcony in his apartment. That's the first time I recall them focusing on the height/expanse of the balcony. And he had that exhausted look about him that I'd imagine one often sees in someone right before the plunge. Just a thought.
Like I said, Don's era has come to a close. With the impending arrival of the 70s, the reign of the alpha males is coming to a close. He'll either find peace soon, or find pavement later.
If you can't draw a crowd, draw dicks on the wall.
