Yeah my wife and I love that show! All three seasons are on Netflix, and it's a good all-around family-friendly show. The acting is decent (most of the show focuses on the kids and their trying to solve small-town mysteries during the onset of the Cold War), the set dressing and the costumes and makeup are straight from the 1960s, and the various plots and story arcs throughout the seasons are intriguing.
All in all a lovely show. The only real downside is that there are only three seasons!
Thanks! The reason I asked was I just received a very cool prop badge from the show. I looked it up and saw it was cancelled and then started to play it and the badge is right there in the intro. Thought I might give it a watch.
