Well, I'm still watching this after 3 episodes. Some minor annoyances: the pilot asking Colette about how old she was when the Nazis came was some of the sloppiest foreshadowing I've seen in a while. And most of the music isn't period, it's from much later in the 1960s. Berlin appeared to be a re-dressed NYC, but they did a decent job of that (putting up a few German-style street signs and the like). Overall, decent enough that I'm not pulling the plug yet.
