It absolutely changes. The macho stuff lasts maybe 1-2 episodes, but after that it becomes clear that all the macho guys are damaged. By season two, the women are running the agency and pushing the series forwards, and the macho men are kind of close to the villains insofar as they unintentionally self-sabotage themselves. By season 4, the only successful men on the show are gay. The macho men are all dead, except maybe one that the writers keep to prove how bad he is, and to provide plot tension.

Partway through season 4 is as far as I got, but if you're big into feminism and space, you'll probably enjoy it even as the plot diverges from "Apollo-13" to science fiction.

I don't know if that's the kind of show you're looking for, but I find it funny for someone to watch only the beginning and label it too macho when the rest of the show clearly hates the macho man stereotype, lol.
