It could be clownish and a caricature. I enjoyed The Road but it makes me think of a critique of sci fi I read once, wherein masculine sci fi novels focus deeply on engineering problems and all but ignore human or environmental ones. Some books tackled this by demonstrating the presumptive and flawed approach sci fi writers take to biospheres / space stations / generation ships for example (Voyage from Yesteryear, A Half Built Garden) where despite all the engineering, the biosphere suffers. I suppose a part of why Dune made such waves was that it took a very human and ecological perspective front and center.

The Road could be seen as overly masculine in its portrayal of a man and his son against nearly the entire world, which is often the fantasy of male prepper types. Some oppositional takes to this would be e.g. Cory Doctorow's Masque of the Red Death, where he presents the dichotomy directly in a post-apocalypse world and argues for the more optimistic outcome, wherein people work together in a non-exclusionary way to overcome whatever the apocalyptic scenario is, which might be considered a more feminine perspective. Others taking that perspective would include Rebecca Solnit in "A Paradise Built in Hell."

In the Too Like Lightning series, Ada Palmer takes on the male/feminine sci fi angle directly by creating a near-utopian society of mostly gender neutral people. At one point in the novel a character argues that in fact they've created a feminine society of women, and therefore aren't prepared to handle the outlier class of people that want to create war, who have for the most part began to present explicitly as men.
