You have no idea what's going on because you're culturally illiterate. Problem no.1 above anything else, it's simply a noun-overload for dipshit zoomers who really don't know anything outside their lived time.
And the thing is, there's no particular source you can go to to fill in your knowledge gaps. Watch TCM for a year maybe? If you don't know who Carey Grant is, no quantity of IQ can help you. And that's basic, basic offhand mentions. If you don't know how wartime british officers talk, the events about which they might talk, there's really no helping you. If you're not acquainted with the time period it's just a bunch of gobbledey gook. Again, the problem here is not even necessarily intellectual.
Pynchon learned all this without an internet, by the way.
