Kind of a strange book, and, even with all the end notes explaining things, felt very out of context to me. It probably was amazing to your 19th-century Russian, or Russian lit nerd even, but I spent the majority of it bemused and confused.
There were some good scenes, and I generally liked the writing style, especially all the analogies, which were quiet funny, as were some of the character studies. Could have lived without the anti-Semitism.
I only read vol 1, as the translators spent most of the intro assuring me that vol 2 (which is fragmentary) wasn't very good.
