The machismo is deconstructed, but the American chauvinism is real - they can't even stick to the premise of the USSR/Soviets being a more credible antagonist to drive the space race forward. They give the US loads of tech upgrades from the space race, but the USSR does not get the same upgrades despite doing the same thing.

The worldbuilding aspects are also kind of weak, with weird Final Destination-esque setpieces, and implausible political-economic just-so-stories to get main characters where the story wants them to be.

All in all, I found it unbearably shallow.
