I have never read a book I hated more than The Brothers Karamazov. I never read a book that depressed me more than Crime and Punishment. No more Dostoevsky for me.
"Russian literature consists of suffering. Either writer suffers, or protagonist, or reader. If all three suffer simultaneously--then it is a masterpiece. In every difficult situation always read Russian classic literature--it is even worse in there."
Edit: except for The Double.
