Started it last night, first two episodes. So far, so good. Like you, I am enjoying the character portrayals and also the political angles. However, I feel the writers are trying too hard with the portrayal of strong female characters. Not complaining about it, just don't think it's accurate. Then again, this is an alternative history narrative so the writers have license.
Speaking of alternative history and political angles, I thought it was clever that Teddy Kennedy didn't go to Chappaquiddick that moon landing weekend. I'm certain the writers are setting him up to run against Nixon in 1972. (No spoilers, please.)
