Cactus .yup, I can sort of agree. ( am also a Ulysses fan).
Moby Dick I resorted in part to audio book in the gym.
Time Traveller's wife, just a non event. Adequate short haul reading.
Catcher in the Rye, agreed with Ds who said puerile and no excuse for boring bad language.
Les Mis. So much better as a musical.
I enjoy Middlemarch though like Jude and Emma it's full of characters I loathe and social embarrassment at which I shudder.
Tess of the Durbeyvilles. Unreadable.
Arcadia. Don't even try. Was once in a seminar with John Carey where we agreed it was truly awful and the rest of the group loved it. Only time I've ever agreed with him.
Much of Our Mutual Friend. Saved by Lizzie.
Did I say The Magic Mountain?
But Clarissa and Arcadia, comprehensible and turgid, are tops.
