We don't get a lot of alternate history shows on TV, so this one is a bit unique on that alone. And, the historical aspects were actually really, really solid...everything that happened was plausible based on the world back then. How they connected to the larger world around the space race was also well done. The acting was largely pretty good, and a few people were really awesome. If anything, how Deke Slayton was handled, from the actor to his story, was spot on perfect (and no one should spoil this plot thread here). If you like sci-fi or space stuff, you really should watch the entire series before declaring it worthless.
