Dostoyevsky's works are amazing without any background knowledge. No 'intellectualism' is required, just a love of stories. With a few tweaks they could be set in a modern era and turned into Netflex series.
War and Peace is considered a challenge because of the rambling philosophical chapters between the main action, but strip those out and you have Gone with the Wind. Easily enjoyed without any extra frontal lobe matter.
One of my mantras as a reader is that I no longer am in school and no one is going to make me write a paper or discuss overriding themes. I can read the way I like and enjoy what I like and if I missed all the mustard seed references than it doesn't matter to me.
I could go into a side discussion on how literature is taught but I'm sympathetic to English curriculum developers who have to give students some books to read and have some criteria by which they can make sure students have read and understood it.
I'm a science fiction fan and I like to approach books as though they were set in Jupiter in the far future. One of my beliefs is that great literature transcends the time and place of where it was written. I haven't been disappointed yet.
It's always worth researching translations to make sure you find the best, most readable one before embarking on a non-English classic.
Surely, it's a matter of taste :-) I've read Crime and Punishment, The Brothers Karamazov, Demons, and The Idiot without particular enjoyment. I would take Tolstoy any day.
And Anna Karenina was in production too...
Readers interested in Dostoyevsky, Tolstoy, or Chekhov are presumably intellectuals. Presumably, they will be familiar with the countless examples from history when, driven by patriotic fervor, countries cleansed themselves from the culture of an adversarial state, including language, literature, music, linguistic borrowings, scientific contributions, common history, etc. etc. Presumably, these potential readers should be sophisticated enough to separate the crude politics of the day from the valuable contributions to the history of art or science.
Is he _really_ interested in the audience whose interest in the 19-th century Russian literature is predicated on the Russian politics of the 21st century? Why does he want to reach this audience? And, more generally, in the environment that is arrogantly dismissive to "old white men" in general, why worry about the readership of Dostoyevsky at all?
