Ulysses! The Joyce one. Honestly I enjoyed it - for how esoteric and sort of distant it is, the base plot itself is kinda mundane so it's not like the base structure of the book is massively hard to follow (especially if you're familiar with The Odyssey) once you get over the constant writing style shifts. It's randomly funny and weirdly relatable (like being stuck in a conversation with a chatty American) and gives you so many reasons to hate the British. I really like how it's adapted the story of The Odyssey and I think more adaptions of Greek works should be like it - an adaption of the themes and vague plot beats rather than just taking the characters and doing whatever the fuck you want with them, and also should have one guy who inexplicably thinks he's actually in an adaption of a Shakespeare play instead.

I will say though, my copy of Ulysses is one third appendix, which explains out the schema and has footnotes for most of the references that will just go right over your head if you don't happen to be James Joyce and I genuinely don't understand how you could read that book without it. It really turns every confusing reference and story moment into something clear and understandable which elevates the text around it. If I didn't have it I most definitely would've dropped the book

Also I'm nowhere near finished but I've started reading Dream of the Red Chamber (aka Story of the Stone) which is an 18th century Chinese novel infamous for being really long (I think it's like over 2k pages? My copy is divided up into like five books) and difficult to follow with way too many characters in it. It's a big long deconstruction of Confucianism and nobility following a chunk of the heavens who's reincarnated into a failing noble family because he wants to see what it's like being human, only to be treated like absolute shit by his family because everyone see him as a divine blessing and want to use and abuse him as much as possible for their own ends. He spends a lot of time around the women of the house and watches their own tragedies unfold, hence the length and excessive characters. Hasn't gotten too bad yet, but I'm also barely into it relatively speaking.
