He was a noted hater of many great authors and works so naming one target of his doesn’t carry much weight

It's true, but he was such a good hater that one has to love him for it.

His criticism of characters being laid bare at the beginning of the novel is fair, especially in Karamazov. Unlike Nabokov I don't think it detracts from the work.
