@Gwenfar Oh, you're right. I was definitely getting an "older SF" sort of vibe from it along with generally thinking I'd have liked it a lot more when it came out. I hadn't connected those two thoughts, nor that the colonialist aspect of this one was so much of a piece with its other flaws.
I feel like it does some questioning of the colonialism, and at least has some female characters who have agency and aren't just there to be a foil for the men. But I am now thinking of it as sort of transitional: it represents some steps forward from bad-old-days SF, but not enough steps that I can enjoy it unreservedly today.
