We're gonna have a couple of rules for this discussion.
You may not vent about hating a difficult book someone else enjoyed. If there's interest (of course there's interest) in a discussion about difficult books you've hated, I'll start it with a different post.
If a book someone else says is difficult isn't difficult for you, don't say it here. Say it somewhere else if you like.
Difficult books I've liked:
The Worm Ouroboros
Jonathan Strange and Mr. Norrell
EDITED TO ADD: By all means, talk about what you liked in the difficult books you liked.
