I'll confess that I watched this primarily because it was produced locally and because it followed something I had been watching on the same channel. But it exceeded my expectations. The acting was good, the writing was very good, and the plot moved along quite well. I've always been interested in a "what if" kind of story, and this develops the premise very well.
Of course, much of my interest was in the fact that I lived through this period and was probably the same age in 1962 as the kids. But don't think the show is only about the kids - the adults are all interesting and they have very real interactions with each other.
The biggest fun for me though was in seeing how goofy people's thinging was back in the days of the cold war. But I also remember my own anxiety over the Cuban missile crisis or over the fact that a major Air Force base 60 miles to the north would be a likely target for nuclear attack. There was a lot of fuzzy thinking with the duck and cover exercises and the basement bomb shelters, but it's easy to see why from a contemporary perspective.
Well worth watching.
