I'm glad it didn't fetishize the 80's too much (the coin on a string is relatively obscure and I loved it though).
Lee Pace is doing a great Don Draper. That's a good thing.
Scoot McNairy is excellent just playing Scoot McNairy however Kerry Bishe's "You're killing yourself inside, husband!" parts were groanworthy. I do like the fact that she's herself an engineer as well.
Mackenzie Davis. Always dug her. I love the part where she calls that dude a fascist for kicking her out of his bar. So good.
Love Toby Huss being all piss and vinegar while looking UP at Lee Pace (holy shit Lee Pace is tall as fuck).
BTW, if you don't recognize the voice, Toby Huss was also General Treister from Venture Bros.
