I recently read a few reviews that seemed to "stand out". I know every work is bound to receive some bad reviews, but a couple of these made me laugh
Jude the Obscure
"The village aesthetic brooding over the village idiot" - Milton Shulman
Ulysses
"In Ireland they try to make a cat clean by rubbing its nose in its own filth. Mr. Joyce has tried the same treatment on the human subject" - George Bernard Shaw
Finnegans Wake
"Obvious schizophrenia" - (unknown psychiatrist)
On the Road
"That's not writing, it's just typing" - Truman Capote
Our Mutual Friend
"To our perception, the poorest of Mr. Dickens' works. And it is poor with the poverty not of momentary embarrassment, but of permanent exhaustion." - Henry James
