"The character is not likable"... I must have read this sentence hundreds of times here on Amazon. Why don't people understand that great novels do not need to have likable characters?
"... the events not interesting". This is a "psychoanalytic" novel - and one of the very first of its kind. This is literature imitating life imitating literature, not a novel full of mysteries and adventures. You don't read this book for the events it tells, but for understanding what human soul is.
