Dostoevsky is hardly difficult in the way that Joyce is. I mean, yes, there’s lots of layers to uncover, but he’s downright comedic when the situation calls of it (e.g. Mitya’s carousing and subsequent arrest in Karamazov is a fine piece of comedy writing and extremely accessible, regardless of the complexity of his motives).
Indeed. I couldn't get more than a few pages into Joyce, but Dostoyevsky's works are a joy. Very relateable human drama. You can enjoy it even on superficial levels, and catch more later on a reread.
