Speak for yourself mister! I personally find the vivid descriptions of Chakas and friends licking moist rocks among the greatest prose ever written in Halo. Up there with "Next time I ride on top" and "I didn't know you, Sarge, but I sure as hell wish I had. You must have been one hardass son of a -Yoink-."
Yeah, and I'd say the same to you, especially when you seem to intentionally looking down on the book by being ridiculous.
Primordium does veer a lot into the descriptive, but that is to be expected when you understand that the perspective is that of ancient de-evolved humans. It's not for everybody, sure, but Primordium is a heck of a lot smarter than people give it credit for.
And yeah, it has prose that is very meaningful and impactful. My favorite being one from Gamelpar that's pretty timeless:
"Gamelpar lifted his lips in a gap-toothed smirk. "Where there is freedom, there will be war," he said. "We covet. We hate. We fight. We die."
