That's probably because you've read it in English. For the life of me I don't get why non-Russian people read Russian classical literature. Just don't. It is true that there aren't really any Western authors of the same stature as Dostoevsky or Tolstoy, but really, you aren't really reading what they wrote. Their work requires quite a bit of thought, and that thought requires quite a bit built-in stuff that a native wouldn't even notice.
30% of the meaning is not there because you don't have the same cultural background. Another 15-20% is lost in translation. What remains is still formidable, but nowhere near as good as the original work. I happen to also have recently re-read Crime and Punishment, but in my native Russian, after a gap of some 25 years. I've found it very vivid, engaging, and full of nuance I just wasn't even able see when I was a teenager. Likewise I have fairly recently re-read War and Peace, and it is now my favorite book of all time. When I was much younger it seemed "too long" and extremely boring, because it requires quite a bit of lived experience to fully appreciate, and not just any experience, but experience that only someone who has lived in Russia for an extended period of time (not necessarily originally Russian) would have. Really fundamental, basic things, which Americans just can't even begin to understand. I.e. how the government is perceived there (hint: Tsar-like figure is still perceived as a desirable thing), what it means to have a land war on your soil (Russia had many, some extremely devastating), Russian ideas about patriotism, yet at the same not liking how they do things over there, Russian fatalism, how women are perceived by men and the other way around, etc, etc.
Having spent 20+ years in the US and having traveled quite a bit, I've recently read The Grapes of Wrath. I liked the book, and the use of language in it (it almost reads like poetry at times), but I very strongly suspect I didn't quite "get" it to the extent that an American would, for the same reasons I alluded to above. And I have vastly more "American" lived experience than most Americans have "Russian".
