This is an insult to the Kennedy family, particularly JFK, Jackie and RFK. The performances are stereoptypical rehashed rubbish we've seen time and time and again. It was a slushy, lazy production lacking any thought, research or structure.
Writing was terrible, accents were hilarious and Greg Kinnear might never recover from it?
If you think this is good... my guess is that you don't watch much quality television.
