Recent reading reading has included Catch-22 and Doctor Zhivago, and TBH, I think they are both slightly overrated.
Read one conversation in Catch-22 where characters are being deliberately obtuse or are simply talking past each other, and you've pretty much read them all. Some of the introductions to characters suffered from logorrhoea, as if Joseph Heller wanted to show off that he'd eaten a thesaurus. And even though it's a satire, some of what Milo Minderbinder gets up to simply stretches credulity.
The acclaim for Doctor Zhivago was, IMHO, more for it being a work of samizdat WRT one or two characters' ambivalence about the revolution. Boris Pasternak's inconsistent use of the different name forms IAW the eastern Slavic threefold custom meant that early on in the book, I was forever having to refer back to the list of characters at the front of the book to remind myself who was being referred to.
The other criticism offered by reviewers that I agree with is the remarkably fortuitous way in which characters' paths intersected. Pasternak might as well have subtitled the book "It's a small world".
YMMV, of course.
