A reader fills me in:

Hollywood blacklisting? That barely scratched the surface last night. It was truly a Sorkin Tour d’ force. It was not just the blacklisting of an innocent, but an innocent WWII vet who was a D-Day platoon leader whose tale of heroism was practically unrivalled among those who stormed the beach that day.
In addition, there was tangent into race relations involving the perceived racism stemming from the dearth of black writers at Studio 60 to write for black performers.
There was not just a swipe at the Red States, but a full blown story about one of the writers’s parents who were visiting from Columbus, Ohio (!) who were so backward they had no concept of what their son did or what the ‘SNL’ show was that he was writing for. So backward were they that – they’re in their ‘60′s mind you – they had no idea who Abbott and Costello were, and had never heard of the ”Who’s on first” routine (this was when the son was futilely trying to find common ground with his yokel parents in order to explain what was going on around them). Hell, I’m only 37 and I know that “Who’s on First” was a radio skit first.
Not only are they so backward that they are completely unable to communicate with their Hollywood son, but the father is particularly verklempt that his Hollywood son is indulging in the Sodom and Gomorrah that is Studio 60 while his brother is “SERVING IN AFGHANISTAN!”
Of course, they later trundle on their way back East, stopping at Yosemite on the way, in their 1980′s era Dodge minivan.
All quite sickening, really. But softened by the luminous presence of Amanda Peet, and so I continue to watch.
