Had a go at it in my youth. Regret to say I never got to the end.
I was on Team Fyodor in my youth, even managing to get through The Brothers Karamazov in a bit over a week (ah, when I had time!) though I never got around to The Devils, The Gambler, or The Idiot back then (almost all the other novels and stories, however).
So now I am making a major effort to tackle the Russian classics I missed at the time, which means reading a lot more Tolstoy. (I did get through The Idiot just a week or so ago, but wasn't that into it actually.)
A barrier between me and Russian authors is that I always feel a bit uneasy that I'm not really getting what was written when I read books in translation.
