IJ is hated for many reasons, only some of which has to do with the actual content of the book:
-Too many people had once read it on Veeky Forums (when the meme trilogy was first forged) and thus it was overdiscussed (however that was time past, and I'd properly assume many new Veeky Forumsizens since haven't touched it
-People go through an intense love hate relationship with the book (a cultic obsession that then leads to a contrarian dislike and aloofness about the book, and then a fond nostalgia about it after a few years)
-It perfectly strikes its target audience of overeducated college age white men, strikes well enough that its a token item in any of their bookshelves and they are identifiable by it
-it is biggest "maximalist" or "postmodern brick" text with perhaps the simplest language (you can meet ordinary people who have read infinite jest cover to cover, but never gravity's rainbow or the tunnel) and has big pull with the upper echelon normies
-there's somewhat of a performative contradiction in the text that many people bring up, Wallace was attempting to overcome the verbal gymnastics and self referential nihilism he saw eroding empathy and sincerity in the real of fiction, but he does so himself from inside the funhouse of weirdly recursive metafiction
-It is arguably also the simplest text in the meme trilogy and thus the easiest for shitposters to glean information about from wikipedia and try to start arguments over
if you like IJ I urge you to also pick up The Pale King
Catch 22, Lord of the Flies, and Of Mice and Men are all pretty good books sure but if you're consulting some kind of "best of" lists you have to be aware that those books are (or were) required reading in some high schools and are thus vastly overrated by people who've never read any books since
you should read:
-The Corrections by Jonathan Franzen
- 2666 by Robert Bolano
- Life: A User's Manual by Georges Perec
- The Wind Up Bird Chronicle by Haruki Murakami
- Ravelstein by Saul Bellow
- Underworld by Don DeLillo
- 4321 by Paul Auster
-Lincoln in the Bardo by George Saunders
- Giles Goat-Boy by John Barth
-The Magic Mountain by Thomas Mann
none of these are foreboding impenetrable masterworks, some of them are fairly heady but they're nice introductions to each of their authors works (many of the authors having more difficult work you can read afterwards)
while reading foreign language classics like you must keep very importantly in mind that there exist multiple translations of important works and that some translations are vastly better than others. Particularly with respect to Russian authors, you should avoid the Pevear and Volokhonsky translations you see waved about everywhere, and consult Veeky Forums or other sources for the best translation
