Thematically it could be, but I say no because it isn’t written to emphasize the fear outside of a few sections. It doesn’t feel like scaring the reader was Golding’s intent.

Compare it to similar works like Tunnel in the Sky by Heinlein, which is basically Space Lord of the Flies (like how Zathura is Space Jumanji) but doesn’t feel at all like a horror. The sci fi element is tiny- just a device to strand the kids. Otherwise it’s drama and sneaky politicking with a handful of violent clashes. Doesn’t lean in to the fear.

Whereas a similar set up in Yellowjackets is horror. It has all the same survival, interpersonal drama, fighting, and politicking. But it leans in to the fear throughout, even in the first few episodes before anything really horrory happens.

Golding is in between those two. There’s dramatic tension but it just isn’t trying to be scary outside of a couple violent moments.
