Fyodor Dostoyevsky is a great Russian author! What is your favorite book?
Hmm. I have a few favorites of his, of course. But nothing beats the Brothers Karamazov. It is the most complete philosophical/psychological picture of the human condition I have come across (whether systematic or novel). Who is your favorite author and what is your favorite book? 
That is a great way to describe the book. It was a good movie but the book was much better.
You liked the movie? That's a surprise. A lot of people disliked it, and I was not a huge fan myself. But glad to hear that someone liked it. What do you think about book adaptations to movies/shows? 
Some are decent others not so much... Fortunes of War was a pretty good adaptation.
I haven't watched that movie, but I love Kenneth Branagh as an actor (he has done a lot in sharing the genius of Shakespeare to a new generation). I think adaptations (even when not as good) are important, because it, at least, brings attention to the work of literature. A lot of book purists hate adaptations, but I think that is a gatekeeping attitude that shouldn't be apart of the book community.  
I agree...What other books by Fyodor Dostoevsky would you recommend? 
I think his next best book would be Crime and Punishment. It is a morally complex tale (as most of his works are), but this brings up a specific situation that makes you think "is this justified or not?". However, I would suggest the short story, "The Dream of a Ridiculous Man". It was the first thing I read by him and I have been addicted ever since. Do you have any authors you would recommend?
